摘要
对不同纯度的铝在轧制状态下加工软化规律及加工软化机理进行了研究及探讨.结果表明:动态回复是加工软化的主要原因.高纯铝在轧制率达80%以上时出现加工软化现象,而纯度较低的铝不发生加工软化.
This paper discusses the working softening regularity of aluminium of differ- ent purity at rolling and the working softening mehanism of high purity aluminium.The results show that the main reason of the working softening is dynamic restoration.Working softening phcnomenon occurs when the rolling rate is over 80% for the high purity alu- minium but not for the lower purity aluminium.
