Solid-State Processing and Manufacturing for Extreme Environment Applications: Integrating Insights and Innovations
This symposium invites presentations on solid-state processing and manufacturing technologies for developing advanced materials via advanced manufacturing routes for extreme environments. The use of advanced materials and the adaption of advanced manufacturing techniques are essential to push the boundaries for the materials to improve their performance and use in harsh environments. The scientific foundation should employ a comprehensive processing-structure-property-performance approach to develop a combined composition-process-microstructure solution to advance the development of existing alloys. Emerging technologies like fusion-based additive manufacturing are constrained by alloys that can be successfully printed and often require additional steps to achieve full density, increasing cost and time for the development cycle.
An alternative is the solid-state techniques promising higher production rates, fully dense products, refined microstructures, and superior mechanical properties. They also facilitate efficient part repair and large-scale fabrication of meter-sized components at higher build rates. Their cost-effectiveness and energy efficiency make them ideal for nuclear applications. Despite increased interest, studies on the performance of solid-state AM materials in extreme environments remain limited. This symposium seeks to exchange knowledge and explore novel materials and techniques developed through solid-state routes for extreme applications. The symposium will feature invited and contributed talks in the following categories:
1. Solid-state processing: Additive manufacturing (Additive friction stir deposition, friction stir additive manufacturing), processing (friction stir processing, solid-state extrusion), cold spray, powder metallurgy, spark plasma sintering, field-assisted processing, hybrid routes, etc., with emphasis on large production rates of rods, tubes, 3D components, and graded materials.
2. Structure: Advanced characterization to quantify microstructural features, texture, dislocation structure, radiation-induced defects, precipitation, segregation, He-embrittlement.
3. Parameters: Stress, temperature, corrosion resistance, oxidation resistance, stress corrosion cracking, radiation dosage.
4. Property: Hardness, tensile strength, ductility, creep, fatigue, creep-fatigue, irradiation resistance, corrosion resistance.
5. Development of new alloys: Discovery, development, and fabrication of new alloys that are difficult to fabricate by conventional methods including oxide dispersion strengthened (ODS) alloys, functionally graded materials, compositionally graded materials, coatings, and multimaterials, metamaterials and architectured materials.
6. Manufacturing autonomy: Digital twinning of the process to optimize the parameters and train the ML/AI model. |
