| 摘 要： | 针对30CrMnTi合金钢进行了相应的淬火和回火工艺试验研究,通过系列实验比较了不同浓度的AQ251淬火液和回火温度对30CrMnTi合金钢热处理后的组织和硬度的影响。结果表明AQ251淬火液在高温阶段600℃和低温阶段350℃有较大冷却速度;随着淬火介质浓度的减小,30CrMnTi合金钢淬火硬度呈上升趋势;在350℃以下回火,回火温度对硬度影响不明显,超过350℃回火,硬度随温度增加降低显著。

| Abstract: | The quench and temper processes of 30CrMnTi steel were researched and the effects of concentration of the(AQ251) quenching liquid and tempering temperature on the microstructure and hardness were discussed.The results show that the cooling rates of AQ251 approach climax at 600℃ in high temperature and 350℃ in lower temperature.The hardness of 30CrMnTi increases with the decrease of the concentration of the quenching liquid.However it decreases obviously with the increase of the temper temperature above 350℃ while it differs slightly under 350℃. |
