چکیده انگلیسی
This study examined the effect of Ca addition on the selective oxidation of the Al3Mg2 phase in an Al-5â¯mass%Mg alloy during oxidation at 400â¯Â°C and 500â¯Â°C for 72â¯h. Ca addition led to the formation of the Al4Ca and Laves_C36 phases besides the primary Al solid solution and Al3Mg2. After the oxidation test, there was no significant oxidation in both the Ca-free and Ca-added alloy samples and no visible change in the surfaces between them at 400â¯Â°C, which is lower than the melting temperature of Al3Mg2 (451â¯Â°C). At 500â¯Â°C, the surface of the Ca-free alloy showed the formation of oxide blisters, which was not observed in the Ca-added alloy. The presence of an Al4Ca phase at the grain boundaries led to the formation of multi-element oxides containing Al, Mg, and Ca, which can contribute to the formation of a compact oxide layer.
