The effect of high pressure heat treatment on microstructure and compressive properties of low carbon steel were investigated by optical microscope, transmission electron microscope, hardness tester and compression test methods. The results show that martensite appears in low carbon steel at 1-5GPa GPa and 950 °C for 15 minutes treatment, high pressure heat treatment can improve the hardness and compressive properties of the steel, the yield strength of the steel increases with increasing pressure, and its compressive properties are better than that treated under normal pressure quenching.
