摘要
采用热膨胀法测试了不同热处理工艺条件下2.25CrlMo0.25V钢的相变温度Ac1和Ac3。结果表明,该钢经退火处理后的相变温度分别为797.1℃和886.2℃,经淬火处理后的相变温度分别为801.3℃和891.4℃,经调质处理后相变温度分别为809.2℃和898.7℃。不同组织对相变温度有影响,实际生产中应考虑热处理对组织和性能的影响。
The critical transformation temperature Ac1 and Ac3 of steel 2.25Cr1Mo0.25V steel under different heat treatment process conditions are studied by thermal expansion method. The results show that the critical transformation temperature of the steel annealed is 797.1 ℃ and 886.2 ℃, the critical transformation temperature of the steel quenched is 801.3 ℃ and 891.4 ℃ and the critical transformation temperature of the steel quenched and tempered is 809.2 ℃ and 898.7 ℃. Different structures affect the critical transformation temperature. So the influence of heat- treating process on the performance and structure should be considered.
