MESSAGE ON ISAM 2019

Dr. Amjad Ali

21st to 25th October 2019, Islamabad

Advanced materials represent conventional or traditional materials with modified or enhanced properties and/or newly developed materials having superior performance in one or more characteristics that are critical for intended novel application. In other words, materials that are utilized in high technology applications are termed as “Advanced Materials”. Advanced materials are used for making useful and value added products such as, wearable electronics, bullet-resistance vest, sports composites, furniture, automobile parts, functional apparel, aerospace, cryogenic to high temperature applications and bla-bla.

The major reasons to focus on advanced materials development are;

Cost Reduction and increased profitability: Advanced materials that are stronger, lighter and more durable will last longer and save money on replacing parts or can compensate for operational and manufacturing challenges unsolved by relatively less functional materials.

loyalty and Increased customer satisfaction: Because of their inherently improved properties, advanced materials can lead to final products that better fulfill customer requirements and contain fewer defects, which will translate into increased competitiveness.

Sustainability and Regularity compliance: Newer and more stringent regulations are making manufacturing and production more and more arduous. Using advanced materials should help companies comply with regulations without sacrificing performance objectives.

In general, materials and systems will need to be smaller, lighter, stronger, more resistant to the environment and longer lasting. Where existing materials do not meet projected requirements, new ones will have to be developed. Where materials are too difficult or costly to produce, new methods or equivalent materials will be needed. At the same time, new or replacement materials will have to conform to increasingly stringent and broadening environmental impact restrictions. Joining technologies for incongruous materials (e.g., metal to polymer) will have to be developed and validated. And where new materials are used, or even where conventional materials are to be used in unconventional or nontraditional ways, it is desirable to understand and predict their behavior to a much greater extent. Aging materials and infrastructure are an increasing problem and impose the challenge to devise methods to inspect, assess their service life or damage criticality, repair, and/or replace dwindling components and materials.

The development of multiple-role elements like integrated or smart structures for next-generation stealth and vibration isolation aircrafts and submarines; health monitoring of naval ship structures and space stations/lunar colonies typically drive device/system performance and reliability. Therefore, capabilities that measure their critical engineering properties, develop the interrelationships among these properties and the process variables, and intelligently control the process and the resulting geometry are indisputably necessary.

The challenges, as well as the opportunities, are in all areas of materials development: synthesis, fabrication, integration, characterization, and inspection. The properties of composites, ceramics, intermetallic, etc., are defined by the process, or even by scale and geometry e.g. microelectromechanical systems (MEMS) or devices, antireflection coatings, nanocrystals and so on. Traditional manufacturing techniques, such as casting and coating are being replaced by the “Digital Manufacturing Systems” that enable users to fabricate freeform materials, which lead to new functionalities and applications. Advanced Robotics and digital Additive Manufacturing (AM), which is a layer-by-layer fabrication approach to create three-dimensional (3D) products with complex geometries, has “digitized everything” in the manufacturing industry. More recently, digital printing of chemically synthesized colloidal nanoparticles has paved the way toward manufacturing a class of designer nanomaterials with properties precisely tailored by the nanoparticles and their interactions down to atomic scales. However, multiple challenges have prevented the broader applications and impacts of the digital manufacturing technologies.

The message here is that “There is no way but to accept the challenge so as to keep up with the growing and diversifying high-tech industry, by mentoring our youth to emerge as a workforce with advanced STEM (science, technology, engineering and mathematics) Skills and high-tech experience to drive it”.  The second part of the message is that, Pakistan Advanced Materials Forum (PAMF) is organizing the 16th International Symposium on Advanced Materials (ISAM-2019) from 21st to 25th October 2019 at National Centre for Physics (NCP), Islamabad, to reiterate its mission to promote advanced STEM Skills in young scientists and engineers. More than three hundred (300) professionals, students and faculty members have registered themselves to participate in the symposium and share their research work and novel ideas at the international platform.

The symposium will provide an opportunity to learn, interact and collaborate with experts from different countries like Australia, China, England, Jordan, Malaysia, Norway, Saudi Arabia and South Korea. “Don’t miss the opportunity”.

ABSTRACTS OF ISAM-2019

SOPHISTICATED ALLOY DESIGN FOR HIGH STRENGTH NATURAL GAS PIPELINE STEELS

  1. Li University of Wollongong, Australia huijun@uow.edu.au

Over the last few decades, specifications of line pipe steels have moved from API 5L X52 to X70 and X80. This improvement in strength and toughness requires a corresponding improvement in the weld metal and heat-affected zone (HAZ). The coarse grained HAZ (CGHAZ) is a special focus of concern. The weldment experiences severe thermal cycles involving high temperatures and cooling rates. Microstructural changes occur, for instance, precipitates coarsen and dissolve, and grain growth occurs within the HAZ surrounding the molten weld bead. A selection of nine heats of line pipe steel from the same project with different Ti and N content were used to evaluate the effects of Ti/N ratio on weld zone microstructure, hardness and prior austenite grain size (PAGS) in the coarse grained heat-affected zone (CGHAZ). It was shown that the microstructure of the base metal (BM) mainly consisted of fine grained polygonal ferrite with fine islands of pearlite. The weld metal (WM) microstructure was predominantly acicular ferrite with a small volume fraction of pro-eutectoid ferrite. The CGHAZ consisted of bainitic ferrite and islands of martensite-austenite. The inside region of the pipe weld zone and base pipe was slightly harder due to the aging effects of the outer weld pass. The prior austenite grain size was shown to be consistent over the range of seam welding conditions and the range of Ti/N from 2 to 4.2.  Centreline segregation has strong influences on the performance of line pipe steels, in present work, the significance and evaluation method has also been investigated, a MATLAB program based on image analysis was developed and was used to evaluate the five Mannesmann standard charts for centreline segregation. Black and white images were generated from the five standard Mannesmann charts and were used for further analysis. Black dots and segments which represent areas of element segregation were identified from the black and white images according to a certain criterion. The segregation severity was evaluated based on the equations which were developed by considering different parameters of the black segments, and certain rules from experts’ experience at steel factories around the world were also used to evaluate the segregation severity. The segregation level for the five Mannesmann charts was calculated based on the equations and the rules to relate segregation severity and macrostructure images. The segregation severity fits well with the Mannesmann charts.

PREDICTING THE MULTIAXIAL RESPONSE OF TI-ALUMINIDE ALLOY AT ELEVATED TEMPERATURES

  1. Nikbin Imperial College, United Kingdom k.nikbin@ic.ac.uk

The evolution of the gas turbine has to a large extent been due to the development of new advanced materials capable of withstanding higher temperatures and thus allowing more efficient operation. An entire family of alloys, the so-called superalloys, based on Nickel and Cobalt has been developed almost exclusively for the gas turbine industry over the last 50 years. These alloys are used for components operating above 550oC such as turbine blades, vanes, ducts, filters, cases, discs and combustion cans. The thermal efficiency of a gas turbine is only around 38 % with a gas entry temperature of 930oC, whilst at 1530oC the efficiency rises to over 50 %, hence there is a strong demand for materials capable of operating at ever increasing temperatures.

In response to this considerable research has and indeed is continuing to be performed on intermetallic materials such as -TiAl. The low-pressure turbine section, where blade temperatures up to 750oC and blade root temperatures of 500oC are commonplace, is seen as a typical environment for this material. -TiAl possesses some particularly attractive properties such as low density (approximately half that of nickel-based superalloys), and good creep resistance, however it presents the engineer with problems not associated with conventional materials.

A UNIFIED MULTISCALE ELEVATED TEMPERATURE DAMAGE AND CRACK GROWTH PREDICTION OF ADVANCED ALLOYS

  1. Nikbin Imperial College, United Kingdom k.nikbin@ic.ac.uk

Determination of good high temperature mechanical and fracture properties of engineering alloys need both advanced material fabrication, testing for material characterization as well numerical predictive methods for failure. A new failure ductility/multiscale constraint strain-based model to predict creep damage, rupture and crack growth under uniaxial and multiaxial conditions is developed by linking globally uniform failure strains with a multiaxial constraint factor. The model identifies a geometric constraint and a time-dependent local constraint at the sub-grain level. Uniaxial and notched data from a range of advanced materials at various load levels and temperatures with substantial scatter are used to derive the appropriate constitutive equations by using a new empirical/mechanistic approach. Constrained hydrostatic development of creep damage at the sub-grain level is assumed to directly relate to the uniform lower-bound creep steady state region of damage development measured at the global level. Uniaxial and notched bar rupture at long terms is predicted based on the initial short-term creep or a representative tensile strength and a multiaxial constraint factor. The model is consistent with the well-known NSW remaining multiaxial ductility creep crack growth model which predicts crack growth bounds over the plane strain/stress states. This model, therefore, unifies the intergranular creep process response over the whole range of uniaxial, notched and crack growth processes which is extremely consequential to simple long term failure predictions of components at elevated temperatures.

FABRICATION OF TI ALLOYS AND INTERMETALLIC COMPOUNDS USING WIRE ARC ADDITIVE MANUFACTURING ROUTE

  1. Li University of Wollongong, Australia huijun@uow.edu.au

Additive manufacturing (AM) builds up a component through the deposition of materials layer-by-layer instead of starting with an over dimensioned raw block and removing unwanted materials, as practised in conventional subtractive manufacturing. With the development of AM technology, the current focus has shifted to producing functional metal components of complex shape that can meet the demanding requirements of aerospace, defence, and automotive industries. Wire and Arc Additive Manufacturing (WAAM) is by definition a wire-feed and arc-based additive manufacturing that uses either the gas tungsten arc welding (GTAW) or the gas metal arc welding (GMAW) process has drawn the interest of the research community in recent years due to its high deposition rate. This technique has been presented to the aerospace manufacturing industry as a unique low cost solution for manufacturing large thin-walled structures through significantly reducing both product development time and “buy-to-fly” ratios. In the present work, an innovative wire-arc additive manufacturing process is used to fabricate Ti alloys, intermetallic compounds in-situ, through separate feeding of pure metal wires into a molten pool that is generated by the gas tungsten arc welding process. This new manufacturing process possesses revolutionary time and cost saving in comparison to traditional methods. Since the brittle nature of intermetallics, the feasibility of this process in fabricating iron aluminide have been firstly investigated in this study. Also, in order to optimize the specific manufacturing process, the influences of the manufacturing parameters, such as deposition current, interpass temperature and torch travel speed, on the geometries, material and mechanical properties have been studied. In addition to the material with consistent chemical composition, a functionally graded material with pre-designed chemical composition gradient was manufactured by the wire-arc additive manufacturing process. The experimental characterizations have demonstrated that the designed chemical composition in the buildup wall can be accurately achieved by adjusting the wire feed ratio of pure metal wires. The microstructure, mechanical properties and corrosion resistance of the additively manufactured intermetallics have been investigated thoroughly.

The original function of the process of plat forming is to develop heavy naphtha (HSRN), coming from the atmospheric unit of distillation with a weak octane number (NO = 44), to obtain a mixture of fuels â number octane raised by catalytically supporting specific groups of chemical reactions. The installation is divided into two sections:  Section hydrobon. Section plat forming.  The rafinat coming from the bottom of column 12C2 to feed the section plat forming, is divided into two parts whose flows are controlled and mixed with gas rich in hydrogen.  Bottom of the column, we obtain stabilized reformat which is aspired by there pump to ensure the heating of the column whereas a part is sent towards storage after being cooled by the air cooler and the condenser.  In catalytic catalyst of reforming, there is voluntarily associated a hydrogenating function – dehydrogenating, brought by platinum deposited, with an acid function brought by the alumina support (Al 2 0 3 . The mechanism of action of this bifunctionnal catalyst depends on the severity of the operation, of the quality of the load and the type of catalyst.  The catalyst used in the catalytic process of reforming is a very elaborate bifunctional catalyst whose performances are constantly improved thanks to the experimental research supported on an increasingly large comprehension of the phenomena.  The American company Universal 0i1 petroleum (UOP) marketed several series of bimetallic catalysts such as R16, R20, R30 and R62 consisted Platinum / Rhenium on an acid support consisted the alumina added with a halogenous compound (chlorine).

Gas pipeline integrity management programs are applied to facilitating implementation of appropriate and timely strategies to ensure that pipeline system is continually operating in a manner that minimizes risk to the community, employees and environment. Asset integrity management can further be described as the continuous assessment process applied throughout design, construction, installation and operations to assure that the facilities are and remain to be fit for the required purpose.   Asset management within the energy pipeline industry is mostly concerned with integrity assurance. Advanced asset information systems collect significant quantities of variable-quality data including performance data, financial data, as well as measurement data in history. These data provide great value when analyzing the remaining useful life of asset and consideration of the influence of maintenance activities so that the asset management strategy is driven by the available data. Pipeline life prediction is integral with determining the optimal inspection intervals and selecting repair or protection actions.   This paper presents methods to utilise gas pipeline asset configuration data and transaction data such as work history and to provide insight as to where risk of asset failure is currently peaking across an extensive asset portfolio. By ranking the likely potential for failure based on undesirable condition results which are reasonably current, it is possible to generate detailed watch lists to consider and then escalate decisions on the appropriate timing for cost effective intervention.
