报告摘要:

Among different processing routes, powder metallurgy and rapid quenching have large potential for development of novel high-performance materials thanks to excellent control over phase and microstructure selection, and related physical and mechanical properties. This overview describes methods and process variables employed for synthesis of advanced nanostructured lightweight metallic materials. These methods include rapid quenching and mechanical attrition for the production of metastable materials, powder consolidation to create bulk specimens with the desired microstructure and properties, and additive manufacturing for fabrication of parts with complex geometries and modulated meso-scale microstructures. Experimental data for the resulting structures for single- and multi-phase materials will be described for selected materials, including nanostructured and ultrafine-grained phases, quasicrystals, composites and metallic glasses, and the mechanisms responsible for phase and microstructure formation and the related properties will be discussed. Consideration of the problems and challenges for bulk processing will also be addressed in order to derive design aspects and processing guidelines for property optimization of nanostructured metallic materials.
