摘要
通过热重分析实验，研究了Ａｌ－Ｍｇ－Ｓｉ合金熔体在高温空气气氛中直接氧化的孕育期与工艺温度及母合金中Ｍｇ、Ｓｉ含量的关系，摸清了铝合金本体氧化的表观活化能与母合金Ｍｇ、Ｓｉ含量的关系。
This article studied the relation of the incubation necessary for the directed oxidation of the molten Al Mg Si alloy at high temperature in the air with the content of Mg and Si in the parent alloyby the TG experiments. It was proved that the directed oxidation of Al Mg Si alloy is consistent with Arrhenius formula. The relation of the nominal activation energy of the bulk oxidation of the aluminum melt with the Mg and Si content of the parent alloy was studied also.
