摘　　要：研究金属磁记忆检测方法在高温环境下的应用。以12CrMoV试件为研究对象,进行短时高温拉伸试验,利用弱磁场测量仪对试件进行检测,分析高温拉伸试验中温度和载荷对金属表面磁场分布的影响。A metal magnetic memory testing method applied in high temperature was studied.12CrMoV was used and stretched in short-time soak,Gauss meter was then applied.The effect on the metal superficial states of the magnetic field,which was produced by temperature and load,was analyzed.

关 键 词：金属磁记忆检测 高温拉伸 应力集中
