Recent studies have shed new light onto the mechanisms that control deformation enabled precipitation in Aluminum and Magnesium Alloys. These studies show how defect structure, density, and distribution can be manipulated to obtain a high number density of nanoscale precipitates and fine solute clusters. However, many challenges remain with designing effective thermomechanical processing (TMP) routes. These include overcoming the competition between recrystallization and precipitation, decoupling the role of dislocations and vacancies in aiding the nucleation, and performing correlative microscopy studies. On the modeling side, there are challenges associated with capturing deformation gradients across multiple length scales and linking them to phase transformation processes. In this talk we will describe links between theory and experiments covering deformation enabled precipitation in Magnesium alloys and we will contrast them with those reported for Aluminum alloys.
