摘要(Abstract)：

测量了两种Cr-Mo系钢的退火态、淬火态和回火态硬度,并运用Hollomon-Jaffe和转变速率关系式分别计算了两种钢的回火激活能。结果表明,在600~700℃之间回火时,含有较多C和碳化物形成元素Cr和V的H10MOD钢激活能高于3Cr-3Mo钢,说明H10MOD钢的回火稳定性高于3Cr-3Mo钢。Hollomon-Jaffe和转变速率关系式均可在一定的温度范围适用,然而转变速率关系式计算得到的激活能数值低于Hollomon-Jaffe关系式计算所得激活能。

关键词(KeyWords)： 热作模具钢;Hollomon-Jaffe关系式;转变速率关系式;激活能
