摘要/Abstract

摘要： 通过正交试验分析了高温预冷淬火工艺对含铌0.044%(质量分数)的中碳微合金钢的显微组织和硬度、强度、塑性、韧性等性能的影响。结果表明,高温预冷淬火与普通淬火相比,可以明显提升钢的硬度;预冷温度提高、回火时间缩短有利于提高中碳铌微合金钢的强度;预冷温度降低、回火时间延长有利于提高中碳铌微合金钢的塑性与韧性。在本试验条件下,获取其最佳强度值的工艺为1000 ℃预冷,200 ℃回火1 h;获取最佳塑、韧性的工艺为900 ℃预冷,600 ℃回火3 h,此时钢断面收缩率为53.8%,断后伸长率为15.1%,冲击吸收能量为96 J。

Abstract: A medium carbon microalloyed steel containing 0.044% niobium (mass fraction) was studied through orthogonal experiments, and the effect of high temperature delay quenching processes on its microstructure, hardness, strength, plasticity and toughness was analyzed. The results show that the hardness of the steel is higher under high temperature delay quenching than that under normal quenching process. Under the experimental conditions, with the increase of the precooling temperature and the shortening of the tempering time, the strength of the steel is improved. Conversely, the plasticity and toughness are improved. The process to obtain the optimum strength is delay quenching at 1000 ℃ and tempering at 200 ℃ for 1 h. The process to obtain the best plasticity and toughness is delay quenching at 900 ℃ and tempering at 600 ℃ for 3 h, the corresponding percentage reduction of area is 53.8%, the percentage elongation after fracture is 15.1%, and the impact absorbed energy is 96 J.
