Trans. Nonferrous Met. Soc. China 25(2015) 3604-3610 Influence of pre-strain and heat treatment on subsequent deformation behavior of extruded AZ31 Mg alloy Hong-bing CHEN1,2, Tian-mo LIU1, Li-wei...: Pre-compression and heat treatment were performed on an extruded AZ31 Mg alloy, and their effects on subsequent deformation behavior were investigated. The results show that at low temperature......

This is because there is no significant change in the shape of the samples before... that during the subsequent extrusion, the nucleation and growth of DRXed grains can be promoted by the strain energy of materials subjected to MDF as a pre-deformation step [30]. Further, according......
