||Until recently, the arguments favoring advanced manufacturing techniques have largely been 1) the ability to build complex parts that cannot be achieved with conventional processes, 2) the reduction of the number of parts in a complex assembly to avoid issues associated with welding and joining, 3) a reduction in cost, and 4) a reduction of materials waste. In this context, alloys that have been considered for techniques such as additive manufacturing have almost exclusively been those developed for standard manufacturing processes, such as conventional steels (i.e., 316L stainless steel), aluminum alloys such those based on Al-Cu-Mg-Sc-Si, Ni-Cr–based superalloys (Inconel 718/625), and titanium alloys (largely Ti-6Al-4V). Challenges associated with achieving controllable microstructures and properties in these technically relevant alloys leads to a pertinent question: Based on new advanced manufacturing strategies, is there a need to develop new materials that are better suited to take advantage of these processes and their parameters? It is anticipated that growth in materials diversity will soon drive the progress of advanced manufacturing technologies. High-performance materials, new alloys for structural and biomedical applications, high-strength and high-radiation-resistant alloys, hierarchically graded materials, and composite materials, among others, have begun to generate interest.
This symposium will highlight recent advances in the design and optimization of materials for advanced manufacturing. Presentations are sought that illustrate paths toward broadening the advanced manufacturing design space to include new, innovative materials, including but not limited to:
• Experiments that explore a broader materials design space, including metals, alloys, ceramics, composites, and polymers
• Combinatorial experimental approaches for materials design and optimization
• Computational methods for design of advanced materials with improved properties
• Experiments and simulations that aid in understanding the role of physical properties on materials design
• Advanced characterization techniques that provide insight for materials design
