Dynamic recrystallization during hot compression of WE54 magnesium alloy

Abstract

The heterogeneity in the microstructure of hot compression samples during dynamic recrystallization of a WE54 alloy containing rate earth metals is studied. The samples show a heterogeneous deformation pattern. After testing, the metal near the periphery of the billet can be seen as the ¿easy deformed region¿ and material near to the geometric center can be seen as the ¿difficult deformed region¿. In other words, the strain is higher in the center and decreases toward its periphery. This has a profound influence on dynamic recrystallization that has been shown by analyzing the microstructures in the same location of the compression sample at different temperatures and at a different locations.
