英文摘要：

Understanding deformation mechanisms is the key to deal with technical problems in the process- ing,application and development of the magnesium alloys. Due to the hcp crystallographic microstructure, deformation mechanisms of magnesium alloys are very complicated, on which researchers are keen to carry on deep and extensive studies. Based on the investigations of the magnesium deformation in recent years and summary of related literatures, the crystal orientation distribution, anisotropy, deformation mechanism and its effect on the mechanical behavior were introduced. The aim was to give a helpful reference to further in- depth studies on deformation mechanisms of magnesium alloys.
