摘　　要：研究了固溶温度对真空熔炼后又进行电渣重熔的 32Mn 7Cr 1Mo 0 .3N奥氏体钢低温韧度的影响。结果表明 :随固溶温度的升高 ,不论是快冷还是缓冷的试样 。The influence of solution temperature on the cryogenic toughness of 32Mn 7Cr 1Mo 0.3N austenitic steel,which was melted in vacuum induced furnace and then remelted in electroslag.The results show that with the rising of solution temperature, the impact toughness of specimen increase obviously,whatever are cooled quickly or slowly.

关 键 词：高锰奥氏体钢 固溶温度 低温韧度 电渣重熔
