The effect of deformation behavior on the in vitro corrosion rate of Mg–2Zn–0.5Nd alloy was investigated experimentally after uniaxial tensile and compressive stress. The microstructure and texture were characterized using electron backscattered diffraction and X-ray diffraction, while potentiodynamic polarization and immersion tests were used to investigate the corrosion response after deformation. The result reveals that applied compressive stress has more dominant effect on the corrosion rate of Mg–2Zn–0.5Nd alloy as compared to tensile stress. Both tensile and compressive strains introduce dislocation slip and deformation twins in the alloy, thereby accelerating the corrosion rate due to the increased stress corrosion related to dislocation slips and deformation twins. The {10\(\bar{1}\)2} tension twinning and prismatic slip were the major contributors to tensile deformation while basal slip, and {10\(\bar{1}\)2} tension twin were obtainable during compressive deformation. The twinning activity after deformation increases with the plastic strain and this correlates with the degradation rate.

在单轴拉伸和压缩应力作用下，通过实验研究了变形行为对Mg–2Z​​n–0.5Nd合金体外腐蚀速率的影响。用电子背散射衍射和X射线衍射表征了组织和织构，同时用电位动力极化和浸没试验研究了变形后的腐蚀响应。结果表明，与拉应力相比，施加压应力对Mg-2Zn-0.5Nd合金的腐蚀速率具有更主要的影响。拉伸应变和压缩应变都在合金中引入了位错滑移和形变孪晶，从而由于与位错滑移和形变孪生有关的应力腐蚀增加而加速了腐蚀速率。{10 \（\ bar {1} \）2}拉伸孪生和棱柱形滑动是拉伸变形的主要贡献者，而基础滑动则是{10 \（\ bar {1} \） 2}拉伸孪生在压缩变形期间可获得。变形后的孪晶活性随塑性应变而增加，并且与降解速率相关。
