【摘要】：采用不同工藝對(duì)3D打印小型3Cr2W8V鋼模具進(jìn)行了熱處理,并進(jìn)行了耐磨損性能和熱疲勞性能測(cè)試與對(duì)比分析。結(jié)果表明:熱處理有利于提高3D打印3Cr2W8V鋼模具的耐磨損性能和熱疲勞性能,優(yōu)選的熱處理工藝為:150 MPa/350℃×1 h熱等靜壓處理后500℃×2 h熱處理的復(fù)合熱處理。與未經(jīng)熱處理的模具相比,復(fù)合熱處理能使模具的25℃磨損體積減小75%,350℃磨損體積減小82%,熱疲勞裂紋級(jí)別從9級(jí)變?yōu)?級(jí)。
[Abstract]:The heat treatment of 3D printed small 3Cr2W8V steel dies was carried out with different processes, and the wear resistance and thermal fatigue properties were tested and compared. The results show that heat treatment is beneficial to improve the wear resistance and thermal fatigue properties of 3D printed 3Cr2W8V steel dies. The optimum heat treatment process is the composite heat treatment of MPa/350 鈩，
