Processing and behavior of nanostructured metallic alloys and composites by cryomilling

摘要: Recent interest in nanostructured materials stems, not only from their potential use a variety of applications, but also the reported discovery novel fundamental phenomena. The consolidation cryomilled powder provides pathway towards large scale manufacturing metallic materials. This approach typically engenders mechanical attrition powders liquid nitrogen, followed by consolidation, using established commercial techniques, such as isostatic pressing and extrusion. In this overview paper, published data are reviewed discussed with particular emphasis on following topics: nanostructure evolution mechanisms; primary secondary processing methods; thermal stability materials; behavior consolidated associated mechanisms Al alloys an effort to shed light into ultrafine grained
