Dislocation movements during creep in a die-cast AM50 magnesium alloy

Tensile creep tests were combined with detailed transmission electron microscopy in order to characterize the dislocation movements during creep of the die-cast AM50 magnesium alloy. TEM observations indicate that dislocations are introduced within the primary α-Mg grain interior in the die-casting process, which consist of both the basal and non-basal segments. The non-basal segments of dislocations, having smoother curvature in as die-cast...
