摘要
本文对 Cr-W-Mn 钢超塑形变热处理的组织进行了微观分析,提出了钢在(γ+c)二相区超塑形变的变形机制模型,并对该钢超塑形变热处理后的力学性能进行了测试。
The structures of steel Cr-W-Mn by superplastic thermo-mechanical-treat-ment have been analyzed.It is shown that model of superplastic deformation mechanism of thesteel is in double phase(γ+c)range.The mechanical properties of the steel by superplasticthermo-mechanical-treatment have been given in this paper.
