Dislocation behavior in a polycrystalline Mg-Y alloy using multi-scale characterization and VPSC simulation
Zhou, Bijin; Wang, Leyun; Jia, Hailong; Zeng, Xiaoqin; Li, Yanjun (Peer reviewed; Journal article, 2022)In this study, the dislocation behavior of a polycrystalline Mg-5Y alloy during tensile deformation was quantitatively studied by an in-situ tensile test, visco-plastic self-consistent (VPSC) modeling, and transmission ... -
Revealing slip-induced extension twinning behaviors dominated by micro deformation in a magnesium alloy
Zhou, Bijin; Wang, Leyun; Jin, Peipeng; Jia, Hailong; Roven, Hans Jørgen; Zeng, Xiaoqin; Li, Yanjun (Peer reviewed; Journal article, 2020)In this study, an in situ SEM/EBSD study on slip-induced extension twinning (S→T) behaviors of a Mg–Y alloy was conducted. It shows that the S→T process cannot be well explained using the classical geometrical compatibility ... -
Revealing the Subsurface Basal <a> Dislocation Activity in Magnesium Through Lattice Rotation Analysis
Zhou, Bijin; Wang, Leyun; Liu, Wenjun; Zeng, Xiaoqin; Li, Yanjun (Peer reviewed; Journal article, 2020)A method was proposed in this study to reveal the subsurface basal dislocation activity in Mg-Y alloy and determine the corresponding Burgers vector. This is achieved by correlating the slip directions of dislocations to ... -
The role of grain boundary plane in slip transfer during deformation of magnesium alloys
Zhou, Bijin; Li, Yanjun; Wang, Leyun; Jia, Hailong; Zeng, Xiaoqin (Peer reviewed; Journal article, 2022)Slip transfer across grain boundaries (GBs) is an important mechanism for HCP metals to accommodate intergranular deformation incompatibility. In this work, an in-situ SEM/EBSD study was conducted to study basal-slip-induced ...
