摘　　要：通过膨胀法测试了Cr5钢过冷奥氏体连续及等温转变曲线,根据测得的CCT和TTT曲线对显微组织与硬度进行了研究,为Cr5钢的热处理与应用提供依据。The curves of continuous cooling and isothermal transformation of supercooling austenite in Cr5 steel were tested by expansion method. The microstructure and hardness were studied according to the measured CCT and TTY curves, which could provide an important reference to the heat treatment and application of Cr5 steel.
