Plastic deformation mechanisms of AZ31 magnesium alloy under high strain rate compression YANG Yong-biao(杨勇彪)1, 2, WANG Fu-chi(王富耻)1, TAN Cheng-wen(谭成文)1, WU Yuan-yuan(吴园园)1, CAI Hong-nian(才鸿年)1... attributed to the difficulty in activating a sufficient number of independent slip and twinning systems. During deformation, plastic strain is accommodated mostly by basal slip and tension twinning......
University of Technology, Changzhou 213001, China) Abstract: The effect of strain strengthening on the fatigue and cyclic plastic deformation of 022Cr17Ni12Mo2 stainless steel was studied. The results show that, the strain strengthening not only improves the yield strength, but also extends the fatigue life of 022Cr17Ni12Mo2. Moreover, the strain strengthening inhibits the cyclic plastic deformation. When......
