摘要：
The twinning behavior of Mg-5.65Gd-3.15Y-0.48Zr(VW53) magnesium alloy in solid solution was studied by compression experiments with different strains at room temperature, and the effects of twinning on microstructure and properties of the alloy were investigated. The microstructure of VW 53 magnesium alloy was observed and analyzed by OM, SEM and EBSD. Vickers microhardness of samples was tested. The results show that { 1012 } tensile twins and { 1121 } tensile twins are mainly produced during the compression process of VW53 magnesium alloy at room temperature. With the increase in strain, { 1012 } twins will nucleate, grow, merge, and even annex the entire grain, while { 1121 } twins will not expand and merge significantly. With the increase in strain, the degree of cross-cutting of twin boundary and segmentation of refined grain increases, which can effectively improve the mechanical properties of VW5 3 magnesium alloy.
