摘要
研究了国产新型冷作模具钢ＬＤ钢（７Ｃｒ７Ｍｏ３Ｖ２Ｓｉ）在超塑性条件下压缩变形的力学特性，得出了其最佳超塑压缩变形的工艺参数．
The mechanic property of compression deformation of LD steel (7Cr7Mo3V2Si),which is a kind of late-model cold-working die steel of home manufacture, has been studied under superplastic condition,and the optimum technological parameters of LD steel compression deformation acquired in this paper.
