在测试了Fe-5%V-5%W-5%Mo-5%Cr-3%Nb-2%Co-2%C(Fe-V-W-Mo)合金的临界点和CCT曲线基础上,研究了淬火温度、淬火冷却方式对该合金组织和性能的影响.研究结果表明,Fe-V-W-Mo合金油冷淬火温度低于1025℃,随淬火温度升高硬度升高,超过1050℃,硬度反而降低.雾冷和空冷淬火时,淬火温度对硬度影响结果相似,获得最高硬度的淬火温度高于油冷时的淬火温度.Fe-V-W-Mo合金油冷淬火淬透性最好,雾冷次之,空冷最差,但是油冷和雾冷差别不大.Fe-V-W-Mo合金红硬性和韧性随淬火温度升高而提高,超过1150℃时,韧性反而降低.最后讨论了Fe-V-W-Mo合金在不同淬火冷却条件下组织和性能变化的原因.
