英文摘要	Through investigating and comparing the microstructure and stress corrosion cracking (SCC) behavior of an as-extruded Mg-6.2Zn-0.8Zr (in wt.%) alloy before and after solid solution treatment (T4), the effects of grain structure on the SCC resistance and cracking modes have been disclosed. Slow strain rate testing (SSRT) results demonstrated that the SCC resistance decreased with the increased fraction of coarse grains. Failure analysis indicated that for the finely grain-structured samples, the cracking mode was dominated by the intergranular cracking. For the "bi-modal" grain-structured samples, the cracking mode was intergranular/transgranular mixed type. For the coarsely grain-structured samples, the cracking mode was transgranular.
