对低碳低合金钢进行淬火-配分-回火(Q-P-T)工艺处理,研究了 Q-P-T 处理后试验钢的显微组织、力学性能以及氢脆敏感性,并与传统淬火回火(Q-T)工艺处理后的进行了比较.结果表明:相对于传统 Q-T 工艺,Q-P-T 工艺处理后的试验钢获得了较多的残余奥氏体,塑性和韧性分别提高了3.5%和27%,氢脆敏感性降低;残余奥氏体对降低氢脆敏感性具有积极作用.

The microstructure,mechanical property and susceptibility to hydrogen embrittlement of a low-carbon and low-alloy steel treated by quenching-partitioning-tempering (Q-P-T)process was studied,and compared with those of the steel treated by traditional quenching-tempering (Q-T)process.The results show that the steel treated by Q-P-T process contained more retained austenite,the ductility and toughness increased by 3.5% and 27%respectively,and the susceptibility to hydrogen embrittlement decreased comparing with that by Q-T process.The retained austenite plays a positive role in decreasing the susceptibility to hydrogen embrittlement.
