摘要
研究了在纯铝（９９．９６％Ａｌ）中加入不同含量Ｆｅ的Ａｌ－Ｆｅ合金加工软化规律，结果表明：纯铝中加入２％Ｆｅ的Ａｌ－Ｆｅ合金，在轧制率达９０％以上时出现加工软化现象；多边化回复是加工软化的主要原因；第二相的存在有利于多边化回复。
This paper is on the laws of the ironing softness of the alloys of pure Aluminum（99．96％Al）added with iron of different content． The result is that the phenomenon of rollingsoftness appears in the alloy of pure Aluminum（99．96％Al）added with Iron（2％Fe） when therate of rolling is over ninety percent the main reason of rolling softness is the multilateralrestoration；the existence of the second phase is advantageous to the multilateral restoration。
