摘　　要：研究了国产新型冷作模具钢LD钢(7Cr7Mo3V2Si)经球化退火与循环退火后的超塑性压缩的力学特性.试验结果表明,经循环退火后的LD钢,其超塑性压缩性能优于球化退火,而且其最佳超塑性压缩的工艺参数也存在差异.The mechanic property of supperplastic compression of LD steel. 7Cr7Mo3V2Si, which is a kind of late-model cold-working die steel of home manufacture, has been studied under superplastic condition after globurizing and cycle annealing. The experimental result has shown that LD steel's supperplastic property after cycle annealing is better than one after globurizing ,and there is difference between each other.
