Ultrafine Grained Phenomena

The post-deformation aging response and underlying precipitation kinetics in ultrafine-grained, age-hardened alloys processed by severe plastic deformation are critical and heretofore poorly understood phenomena that ultimately influence mechanical behavior.Precipitation phenomena in an ultrafine-grained Al alloy,,01-04-2013· Ultrafine-grained (UFG) and coarse-grained (CG) Al 7075 alloy bulk materials have been fabricated by cryomilling, consolidation and subsequent artificial aging. The precipitates have been characterized by TEM, STEM and EDS, and the following conclusions can be drawn from the experimental observations: •Precipitation phenomena in ultrafine grained Al–Mg–Si,,15-01-2016· The aging curve obtained for CG materials and its relation with precipitation phenomena are well known therefore it will not be discussed here, see Refs. , .
