摘要/Abstract

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。

Abstract:

The critical transformation temperature Ac1 and Ac3 of steel 2.25CrlMo0.25V 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 [KG*4]temperature [KG*4]of [KG*4]the [KG*4]steel [KG*4]quenched [KG*4]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.
