摘要

以42CrMo模具钢为研究对象

采用拉伸试验、冲击试验、硬度测试和显微组织分析等方法

研究了淬火温度和回火温度对模具钢组织与力学性能的影响。结果表明

200℃低温回火时

随着淬火温度升高

模具钢的抗拉强度先上升后降低

而伸长率、断面收缩率、冲击韧度呈现下降趋势;600℃高温回火时

随着淬火温度的升高

模具钢的抗拉强度在1 040℃前略有降低

而伸长率、断面收缩率、冲击韧度和硬度整体呈现下降的趋势。200℃低温回火后的模具钢的强度满足要求

但是伸长率和冲击韧度均低于标准要求;600℃高温回火后

模具钢的强度、塑性和韧性都能满足冷作模具钢对基材的要求。

Abstract

Effects of quenching temperature and tempering temperature on 42 CrMo cold working die steel were investigated by tensile testing

impacting testing

hardness measurement and microstructure observation.The results show that

with tempering at 200 ℃

with the increase of quenching temperature

the tensile strength is increased firstly and then decreased

while

elongation

section shrinkage and impact power are decreased.With tempering at 600 ℃

with the increase of quenching temperature

the tensile strength of die steel is reduced lightly ahead of 1 040℃

while the elongation

section shrinkage

impact and hardness are decreased.After 200 ℃tempering

the strength of the steel mold meet the requirements

however

the elongation and impact power energy are lower than the standard requirements.After tempering at 600 ℃

the strength

plasticity and toughness meet the requirements of cold work die steel substrate.
