摘要	Through exploring the stress corrosion cracking (SCC) behaviors of the as -cast Mg-8%Li and Mg-8%Li-6%Zn-1.2%Y alloys in a 0.1 M NaCl solution, it revealed that the SCC susceptibility index (ISCC) of the Mg-8%Li alloy was 47%, whilst the ISCC of the Mg-8%Li-6%Zn1.2%Y alloy was 68%. Surface, cross-sectional and fractography observations indicated that for the Mg-8%Li alloy, the alpha-Mg/beta-Li interfaces acted as the preferential crack initiation sites and propagation paths during the SCC process. With regard to the Mg-8%Li-6%Zn-1.2%Y alloy, the crack initiation sites included the I -phase and the interfaces of I-phase/beta-Li and alpha-Mg/beta-Li, and the preferential propagation paths were the I-phase/beta-Li and alpha-Mg/beta-Li interfaces. Moreover, the SCC of the two alloys was concerned with hydrogen embrittlement (HE) mechanism. (c) 2022 Chongqing University.
