摘要
通过对DIEVAR热作模具钢分别在1020、1030和1050℃进行淬火,然后回火热处理,并利用热力学计算软件Thermo-Calc对其进行热力学计算,研究了热处理工艺对DIEVAR钢组织性能的影响。研究表明:在1020℃淬火处理下,碳化物主要为MC、M_(23)C_6和M_2C,模具钢硬度最低;在1030℃淬火处理下,碳化物主要为MC、M_(23)C_6和M2_C,模具钢硬度最高,为537. 23 HV0. 2,耐磨性最好,冲击性能较低;在1050℃淬火处理下,碳化物主要为MC、M_(23)C_6和M_6C,冲击性能最高,为11. 97 J,综合性能较好。
The DIEVAR hot working die steels were quenched at 1020 ℃,1030 ℃,1050 ℃,and then tempered,and Thermo-Calc software was used to calculate the thermodynamics. Effect of heat treatment on microstructure and mechanical properties of DIEVAR hot working die steel was researched. The results show that after quenching at 1020 ℃,the carbides are MC,M_(23) C_6 and M_2 C,the hardness of die steel is the lowest; after quenching at 1030 ℃,the carbides are MC,M_(23) C_6 and M_2 C,the hardness of die steel is the highest,537. 23 HV0. 2,the wear resistance is the best,and the impact performance is low; after quenching at 1050 ℃,the carbides are MC,M_(23) C_6 and M_6 C,the impact property is the highest,which is 11. 97 J.
