【摘要】 研究了三种纯度的铝及其Ａｌ２％Ｆｅ合金在室温轧制状态下的加工软化行为及软化机理。试验证明：９９．９９６％Ａｌ当轧制率为８０％以上时出现加工软化现象；９９．９６％Ａｌ和９９．６％Ａｌ不发生加工软化。用９９．９９６％Ａｌ配制的Ａｌ２％Ｆｅ合金当轧制率为６０％以上时出现加工软化；用９９．９６％Ａｌ配制的Ａｌ２％Ｆｅ合金当轧制率为９０％以上时出现加工软化；用９９．６％Ａｌ配制的Ａｌ２％Ｆｅ合金不发生加工软化。室温回复是加工软化的主要原因；Ｆｅ有净化铝基体的作用；弥散的第二相有利于室温回复更多还原

【Abstract】 The work softening behaviors and mechanisms of three kinds of pure aluminium and three Al 2%Fe alloys in the rolling state at room temperature were studied. the results show that when the rolling ratio is over 80%, there occurs work softening in the 99.996%Al but not in the 99.96%Al and 99.6%Al; that there occur work softening in the Al(99.996%)-2%Fe alloy when the rolling ratio is over 60% and in the Al(99.96%)-2%Fe alloy when the rolling ration is over 90%, but not in the Al(99.6%)-2%Fe alloy. The main reason of work softening is room temperature recovery which is caused by the dispersive second phases.更多还原
