摘　　要：通过对比5CrMnMo钢经常规淬火热处理和过热淬火热处理后的力学性能,发现过热淬火热处理使5CrMnMo钢的断裂韧性得到大幅度的提高,同时5CrMnMo钢的使用性能也得到提高,模具的使用寿命可提高2.5倍。The mechanical prpoerties comparison of 5CrMnMo steel aider normal hardening treatment and overheat hardening treatment was carried out. The results show that overheat hardening treatment can greatly improve the fracture toughness of 5CrMnMo steel. Meanwhile, the work properties of 5CrMnMo can also be promoted, and the worklife can be lengthened by 2.5 times.
