by optical microscope (OM) and transmission electron microscope (TEM). The results show that twin is primary deformation mechanism and the size of twins is larger at the initial stage of compressive deformation, however, these larger twins will be fragmented and become small under large deformation. With the increasing of strain, some twins cross each other and dynamic recrystallization (DRX......
) Abstract: The selection law of deformation twinning variants at elevated temperature in Mg-Gd-Y-Zr alloy was investigated. The microstructures containing deformation twins were prepared by compressing as-cast Mg-Gd-Y-Zr alloy at 350 ℃ and low true strain of 0.05. The observed {} twins were characterized by electron backscatter diffractometry (EBSD) and transmission electron microscopy (TEM......
