摘要：

The addition of zinc is effective in improving creep strength of Mg-Y solid solution alloys at temperatures 550-650 K because zinc suppresses the non-basal slip that operates predominantly at such temperatures. This suppression is caused by the formation of planar defects on the (0 0 0 1) plane and confinement of dislocations in the basal plane due to a decrease in stacking fault energy.
