摘要
研究了渗碳后深冷处理对20钢机械性能的影响，分析讨论了深冷处理的作用机理。实验结果表明，20钢渗碳淬火后经深冷处理，其硬度、强度及韧性均有不同程度的提高。
The effect of deep cooling treatment after carburizing on properties of 20 steel is studied and the effect mechanism of the deep cooling treatment is analyzed. The result shows that after the deep cooling treatment thehardness,the strength and the toughness of 20 steel carburized are increased.
