embrittlement (HE) theory. Based on the fracture morphology of samples, there exist two kinds of SCC: Transgranular SCC (TGSCC) and intergranular SCC (IGSCC). TGSCC is a major mode of SCC. Most Mg alloys have HCP crystal structures, which are susceptible to cleavage due to the less slip systems available. For example, pure Mg suffers TGSCC, and Mg alloys suffer TGSCC......
