Abstract
The effect of Y addition on the slip behavior of an edge dislocation on basal, prismatic and second-order pyramidal slip planes of Mg has been investigated using a molecular dynamics simulation. It is found that Y increases the critical resolved shear stress of basal slip more than that of non-basal slip and eventually reduces the difference in the CRSS between different slip systems, which is proposed as the reason for the experimentally reported activation of (c + a) slip in Mg-Y alloys.
