摘要(Abstract):
在测试了Fe5%V5%W5%Mo5%Cr3%Nb2%Co2%C(FeVWMo)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,FeVWMo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。FeVWMo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。FeVWMo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FeVWMo合金在不同淬火冷却条件下组织和性能变化的原因。
