Basal and non-basal dislocation slip in Mg-Y

In this study a detailed analysis of the activated dislocations and slip systems via post-mortem TEM and SEM-EBSD based slip band analysis in 3% deformed Mg-3 wt% Y is presented. The analysis reveals a substantial activity of pyramidal dislocations with different Burgers vectors. The obtained dislocation densities and active slip systems are discussed with respect to atomistic simulations of non-basal dislocations in hcp Mg.
