摘要
研究了９ＳｉＣｒ钢超塑形变热处理的显微组织，分析了钢在（γ＋ｃ）二相区超塑形变的特点，提出了超塑形变的微观机制模型，并对超塑形变热处理后的力学性能进行了测试。
The structiire of steei 9SiCr bysuperplastic thermo-mechanical-treatment has been analytal. It is shown that model of superplastic defromation mechanism of the steel in double phase(γ+ C)range is propcoed,The mechanical properies of the steel by soperplastic therrncan-mechanical-treatment have been given in this paper.
