摘要
用膨胀仪和Ｘ射线衍射仪对铬锰氮双相（Ｍ＋Ａ）不锈钢过冷奥氏体在Ｍｓ点附近的热稳定性进行了定量研究。结果表明，０Ｃｒ１３Ｍｎ８Ｎ钢在Ｍｓ点附近等温停留时出现显著的热稳定化现象，在１７０℃和１００℃等温停留所引起的奥氏体增加量最大值分别达到２０．２％和１１．１％。
The thermal stability of undercooled austenite was investigated quantitatively by the use of dilatometer and X ray diffractometer (XRD) for a CrMnN dual phase (M+A) stainless steel.The results show that there exists distinct thermal stability after holding at the temperature around Ms in 0Cr13Mn8N steel,holding at 170℃ and 100℃,the increment maximum of austenite volume fraction is 20.2% and 11.1% respectively.
