Research Progress on Fatigue Behavior of Wrought Magnesium Alloy

Research progress on the fatigue behavior of wrought magnesium alloys is summarized on the basis of fatigue cyclic deformation response, fatigue life, fatigue crack initiation and propagation, etc. The effects of loading condition, environment and surface state on the fatigue behavior of wrought magnesium alloys are described emphatically. It is proposed that the methods including rare earth elements addition, shot peening, surface rolling and appropriate heat treatment can improve the fatigue strength and prolong fatigue life of wrought magnesium alloys. The advantages and disadvantages of these methods are analyzed. The development of fatigue research on wrought magnesium alloys is prospected.
