摘要
采用"锻热调质预处理+去应力退火+真空高压气体淬火+三次高温回火+RE-N-C-B-O-S多元共渗"复合强化工艺,对4Cr5MoSiV1钢进行热处理强化工艺研究。对比实验结果表明,复合热处理强化后的力学性能明显改善,模具寿命提高了4～5倍,取得了比较好的效果。
The heat treatment strengthening process for 4Cr5MoSiV1 steel was studied through the compound strengthening heat treatment technology of the ＂pretreatment of hot-forging quenching and tempering treatment ＋ stress relief annealing ＋ vacuum heat treatment at high pressure gas quenching ＋three times high-temperature tempering ＋ RE-N-C-B-O-S multicomponent permeation＂,Comparative test results show that the mechanical properties significantly improve after strengthening heat treatment.The die life increases by 4 - 5 times,and achieves the better results.
