摘要/Abstract

摘要： 采用新型多循环淬火-配分-回火(Multi-cycle quenching-partitioning-tempering, MQPT)工艺对30CrNiMo钢板进行处理,并对其抗爆轰性能进行分析。通过与常规工艺处理30CrNiMo钢板进行抗爆轰对比试验,结合有限元方法对爆轰过程进行模拟分析,利用微观组织表征手段,对MQPT处理增强30CrNiMo钢抗爆轰性能的机理进行探讨分析。结果表明:在6 kg的TNT当量爆轰条件下,相比于常规工艺,MQPT处理30CrNiMo钢板的变形量减少32.7%;MQPT处理30CrNiMo钢组织为细晶马氏体+薄膜状残留奥氏体,基体强化以及残留奥氏体的TRIP效应使得MQPT处理30CrNiMo钢获得更好的抗爆轰性能。

Abstract: Anti-detonation property of 30CrNiMo steel plates subjected to a novel multi-cycle quenching-partitioning-tempering (MQPT) process was investigated. Through the anti-detonation comparison test with the conventional process treated 30CrNiMo steel plate and combined with the finite element method to simulate the detonation process, the mechanism of MQPT process enhancing anti-detonation property of the 30CrNiMo steel was discussed and analyzed by means of microstructure characterization. The results show that under the condition of 6 kg TNT equivalent detonation load, the deformation of 30CrNiMo steel plate treated by MQPT process is reduced by 32.7% compared with that of conventional process. The microstructure of the MQPT treated 30CrNiMo steel is fine-grained martensite+film-like retained austenite. The matrix strengthening and the TRIP effect of retained austenite make the MQPT treated 30CrNiMo steel obtain better anti-detonation property.

Key words: MQPT process, anti-detonation property, retained austenite, carbides, strengthening and toughening mechanism
