摘要
研究了渗碳＋等温淬火及稀土－碳共渗＋等温淬火的复合强韧化处理对２２ＳｉＭｎＮｉ２ＣｒＭｏＡ钢组织和性能的影响．试验结果表明，用２２ＳｉＭｎＮｉ２ＣｒＭｏＡ钢制作的液压凿岩机钎尾，采用上述复合强韧化处理工艺，其平均使用寿命较常规热处理者提高５～６倍．
The effect of duplex stiengthening and ductilizing treatment of carbonizing +austempering and rare-earthcarbonizing+austemper on microstructure and properties of 22SiMnNi2CrMoA steel was investigated. The result showed that,with duplex strengthening and ductilizing treatment, the life of shank adapter made of 22SiMnNi2CrMoA steel was 5￣6 times of that with ordinary heat treatment.
