摘要
采用光学显微镜、硬度计及压缩试验方法研究了高压热处理对Q235钢压缩性能的影响。结果表明,Q235钢经1～5GPa压力、950℃保温15min处理后组织中出现马氏体组织,高压热处理能提高Q235钢的压缩性能,且屈服强度随压力的升高而增大,其压缩性能优于常压淬火处理的。
The effects of high pressure heat treatment on the compressive properties of Q235 steel were investigated by OM, hardness tester and compression test methods. The results show that martensite appears in Q235 steel after at 1-5 GPa and 950 ℃ for 15 rain treatment. The high pressure heat treatment can improve the compressive properties of Q235 steel, the yield strength of the steel increases with pressure increasing, and its compressive properties are better than that treated under normal pressure quenching.
