The stress corrosion cracking (SCC) behavior of an as-cast AZ91 magnesium alloy in 0.1 kmol/m³ Na₂SO₄ solution was investigated using slow strain rate test (SSRT). The results showed that both the uncharged and charged AZ91 alloy occurred transgranular stress corrosion cracking (TGSCC), which were characteristic of large-plane cleavage fracture. Pre-charging had little influences on mechanical properties. It indicated that hydrogen embrittlement (HE) was the main mechanism for the SCC of AZ91 alloy in 0.1 kmol/m³ Na₂SO₄ solution.
