Dislocation behavior in a polycrystalline Mg-Y alloy using multi-scale characterization and VPSC simulation
文献摘要：
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 trans-mission electron microscopy(TEM).The results of the in-situ tensile test show thatdislocations contribute to most of the deformation,while a small fraction ofdislocations are also activated near grain boundaries(GBs).The critical resolved shear stresses(CRSSs)of different dislocation slip sys-tems were estimated.The CRSS ratio between prismatic and basaldislocation slip in the Mg-Y alloy(～13)is lower than that of pure Mg(～80),which is considered as a major reason for the high ductility of the alloy.TEM study shows that thedislocations in the alloy have high mobility,which also helps to accommodate the deformation near GBs.
