MS&T25: Materials Science & Technology: Sintering and Related Powder Processing Science and Technologies: Organized by Charles Maniere; Eugene Olevsky; Ricardo Castro; Elisa Torresani; Diletta Giuntini; Wolfgang Rheinheimer

The development of new sintering techniques, such as field assisted sintering, spark plasma sintering, flash sintering, laser flash sintering, and cold sintering, has led to material consolidation at significantly lower temperatures and shorter times. Microstructure formation and corresponding structure-property relations of materials consolidated using these new techniques need to be determined for the optimum performance of materials. Tailoring the materials’ sintering behavior, microstructure, grain boundary structure, local defect distribution, space charges, anisotropy of transport processes at interfaces, and texture enables new applications in various fields of structural and functional materials. This symposium covers the fundamental understanding of sintering and grain growth in functional materials as well as their application to current technological challenges. Special emphasis is on new sintering techniques that go beyond traditional thermal processing and the active mechanisms enabling these new techniques. Accordingly, this symposium welcomes talks on basic science topics and modelling/simulation approaches. We also encourage talks on challenges in practical applications of sintering science, e.g., sintering and co-firing of multi-material laminate structures for use in solid state batteries. A major goal of this symposium is to promote the transfer knowledge between modelling, basic science, processing science and applications.

2024 TMS Annual Meeting & Exhibition: Functionally Graded Materials, Coatings and Claddings: Toward Microstructure and Property Control: Organized by Aurelien Perron; Kaila Bertsch; Emma White; Iver Anderson; Timothy Prost; Matthew Dunstan

Most industrial applications such as the aerospace, automobile, biomedical and defense areas need materials that must operate in increasingly extreme and complex environments. Usually no single existing alloy can meet all the requirements of a desired system component. Thus, the successful design and processing of a gradual change in composition and microstructure, and therefore properties, over the whole material is gaining considerable attention in materials science and engineering. Graded materials, coatings and claddings allow for unique combinations of properties to enable various harsh environment, functional and structural applications. In practice, functionally graded materials (FGMs) are often susceptible to processing defects linked to prohibitively time-consuming, empirical process development without the ability to predictively determine and/or rapidly screen experimentally viable pathways (composition and process parameters) to optimize their production. Due to these limitations, the actual performance of FGMs, relative to conventional parts, remains to be validated and optimized. This symposium focuses on all aspects of the science and technology, from fundamental science to industrial applications, that will enable control of the microstructure and properties of graded materials coatings and claddings, including: thermodynamic, kinetic, property, and microstructure evolution simulations; rapid processing; in situ characterization; and understanding defect formation. Many types of gradient systems are of interest, including from one alloy composition to another, from metals to ceramics, and from intermetallics to metals. Advances in coating technologies, new compositions of coatings, and advanced manufacturing techniques are of interest. Specific topics include, but are not limited to: • Fundamental issues and underlying mechanisms in processing FGMs, coatings, and claddings • Development and demonstration of computational-experimental platforms to produce viable graded components ready for various types of advanced testing • Novel graded material combinations, coatings, and claddings for targeted applications (i.e., optimized mechanical, functional and corrosion properties) • Understanding of solidification, phase stability, and phase transformation in FGMs • Computational prediction of optimal material gradients and properties with minimal processing defects, such as porosity • Advanced processing methods for FGMs, coatings, and claddings: additive manufacturing, physical vapor deposition, pack cementation, slurry c coating, powder-based laser deposition, cold spray, thermal spray, and friction stir processing • Novel techniques and characterization methods for rapid FGM, coating, and cladding optimization

2024 TMS Annual Meeting & Exhibition: Ultrafine-grained and Heterostructured Materials (UFGH XIII): Organized by Megumi Kawasaki; Penghui Cao; Mostafa Hassani; Rajib Kalsar; Nilesh Kumar; Praveen Kumar; Dmytro Orlov

Ultrafine-grained and heterostructured (UFGH) materials have been drawing great attention from the materials research community because of their superior mechanical and functional properties. In practice, heterostructures involving an architecture microstructure, such as coarse-grained colonies dispersed in fine-grained matrix, multi-length scale twins packed in predetermined fashion, impregnation of transformational phases into non-transformational phases, etc., can produce outstanding combinations of mechanical properties that are not accessible to materials having homogeneous microstructure. Formation of heterostructures enables a new perspective to further enhance the properties of UFG materials produced by severe plastic deformation and other processing methods. Heterostructured materials can be produced using industrial facilities for large-scale production at low cost. A continuous effort has been made in the research field dealing with processing of UFGH materials and a significant number of studies have been conducted to understand the underlying mechanisms that control the mechanical behaviors of such materials. This symposium focuses on all aspects of the science and technology of UFG and heterostructured materials and covers a broad scope, ranging from fundamental science to their industrial applications. Specific topics include, but are not limited to: • Fundamental issues in processing of UFGH materials including, but not limited to, medium to severe plastic deformation techniques • Deformation mechanisms of UFGH materials • Novel UFG and heterostructures • Mechanical and physical properties of UFGH materials • Performance of UFGH materials in extreme environments (irradiation, thermomechanical, corrosion, etc.) • Multiscale modeling of deformation and fracture of UFGH materials • Emerging processing methods for UFGH materials, such as powder processing and rapid-solidification, mechanical and/or thermal processing • Novel techniques to characterize the behaviors and properties of UFGH materials

Furthermore, the green part additive technologies build on existing process technology from the powder materials and ceramics, which enable the additive processing of non-weldable materials. These processes include but are not limited to: binder jetting, material extrusion, material jetting, bound filament process, nano-Inkjet printing. However, these processes introduce other challenges such as: feedstock development, alloy design, depowdering, powder recycling, binder design, debinding, process modeling, microstructural development, sintering distortion, sintering support structure design. This symposium will explore the interrelationships between the various aspects on the process variables, properties, application performance, economics and functionality of these non-beam additive processes.

2021 TMS Annual Meeting & Exhibition: Powder Materials for Energy Applications: Organized by Kathy Lu; Eugene Olevsky; Hang Yu; Ruigang Wang; Isabella Van Rooyen

In the complex web of energy resource, production, storage, use, and efficiency, materials play a critical role as diverse and far-reaching as energy itself. Powder materials are part of the fundamental science and technology underlying the production of energy, including both conventional and renewable energy sources. Increasing demand for energy and the public’s desire to enhance environmental quality all point to the need for better and newer powder materials. This symposium will cover powder material issues related to energy. It will consider all aspects of powder material processing and property studies with energy applications as the main objective. It includes powder synthesis, forming (including additive manufacturing), sintering, and property evaluation. Powder materials that can deliver outstanding harsh environment properties are especially of high interest. The symposium covers advances in theory, modeling, and computation while in parallel developing cutting-edge experimental techniques and approaches to understand and characterize powder materials in demanding conditions. Both theory and modeling and experimental efforts in powder materials synthesis, processing, characterization, and performance evaluation will be covered.

2020 TMS Annual Meeting & Exhibition: Additive Manufacturing: Alternative Processes (Beyond the Beam): Organized by Paul Prichard; Matthew Dunstan; Peeyush Nandwana; Nihan Tuncer; James Paramore

Additive manufacturing comprises a breadth of processes, which have significant economic potential and technical challenges. Significant resources have been committed to laser powder bed fusion and electron beam powder bed fusion processes. However, additive processes which produce green components and require consolidation processes such as sintering and HIP eliminate many short comings such as slow build rates, residual stress and print support structures. In addition, the green part additive technologies build on existing process technology from the powder materials and ceramics, which enable the additive processing of non-weldable materials. These processes include but are not limited to: binder jetting, material extrusion, filament process, nano-Inkjet printing and selective laser sintering. However, these processes introduce other challenges such as: feedstock development, alloy design, depowdering, powder recycling, binder design, debinding, full consolidation, microstructural development, sintering distortion, sintering support structure design. This symposium will explore the interrelationships between the various aspects on the process variables, properties, application performance, economics and functionality of these non-beam additive processes.

2020 TMS Annual Meeting & Exhibition: Low-cost Titanium: 'Affordable Ti': Organized by Ramana Reddy; M. Ashraf Imam

Titanium and titanium alloys are used in many demanding applications in aerospace, automotive, biomedical and terrestrial systems because of their excellent combination of mechanical properties and corrosion resistance. However, titanium alloys are excluded from many applications because of their high cost- a result of an energy intensive extraction process and complex fabrication sequence to mill products. This is particularly true in the cost obsessed automobile industry; albeit some in-roads are now being made even into the family car. In the proposed six-session symposium, papers addressing all aspects of cost reduction in titanium and its alloys will be presented, and proceedings will be published. The various segments of titanium technology to be covered will include, but not be limited to: extraction (with emphasis on innovative and low cost Kroll approaches) new lower cost alloys, creative melting including cold hearth approaches, near net shape techniques (including powder metallurgy variants such as near net shapes, spraying, laser forming, and casting approaches), additive manufacturing, biomedical applications, processing/fabrication advances such as warm drawing, extrusion, superplastic forming (also in combination with diffusion bonding), high speed machining and knowledge based processing with emphasis on computer aided approaches, better process control including enhanced inspection methods, and creative designs such as functionally graded materials, porous alloys and infiltrated concepts.
