| 摘 要： | 本文对Ｃｒ１２钢深冷处理后力学性能变化做了研究，试验结果表明．深冷处理可以不同程度地提高Ｃｒ１２钢的硬度与耐磨性．而Ｃｒ１２钢淬火回火后再进行深冷处理可使冲击韧性提高．同时，淬火加热温度对深冷处理效果亦会产生影响．

| Abstract: | he mechanical properties of Cr12 steel after cryo-treatment have been investigated in the report. The results reveal that the cryo-treatmect can to some extent, improve the hardness and the wear resistance of Cr12 steel. Moreover,the charpy toughness of the steel increases after quenching, tempcring and cryotreating. Meanwhile,the effect of cryogenic treatment depends upon the heating temperature for quenching. |
