摘　　要：对工业纯铁以不同的工艺进行循环热处理 ,发现以 940℃两次循环热处理得到的晶粒尺寸最小而且比较均匀 ,同时得到的特征塑性 (m)也最大。It is discovered that very small and well distributed grain is obtained after cycle heat treating with 2 at 940℃time for industrial pure iron,and characteristic plasticity also is greatest.Reason of unstable property of the sample obtained by other technology is mixgrain.

关 键 词：工业纯铁 塑性 循环热处理
