The microstructure of low carbon steel SS400 deformed at different temperatures and reheated to austeniteregion after deformation was studied.
对不同温度下变形和变形后再加热到奥氏体区的低碳钢SS40 0的显微组织进行了研究。
2
At high temperatures, the material is entirely austenite, but upon cooling enters a region where the stable phases are ferrite and austenite.
在较高温度时，这种材料全部是奥氏体，但随着冷却就进入到铁素体和奥氏体稳定状态的区域。

The influence of the rate of heating at phase transformation region, temperature of austenitizing and holding time on the austenite grains are studied.
