对40Cr钢单相奥氏体区和双相区加热等温淬火组织分析表明:由于奥氏体成分、状态不同,经相同温度等温后获得不同类型组织.贝氏体、马氏体转变区域移向更低的温度.
The austempering microstructure analysis of single phase austenite and dual phase heating in 40Cr steel shows that different types of microstructure are obtained after the same temperature isothermal due to the different composition and state of austenite.The bainite and martensite transformation direction Lower temperature.
