【摘要】：通過添加Cr、Mo、Ni、W、V等元素,設(shè)計(jì)和制備了熱作模具鋼樣品。研究了熱處理工藝對(duì)熱作模具鋼性能的影響。結(jié)果表明:1025℃淬火+550℃回火后的模具鋼樣品性能最佳,其抗拉強(qiáng)度為1785.1 MPa,屈服強(qiáng)度為1573.1MPa,硬度為50.9 HRC。當(dāng)試驗(yàn)溫度為600℃時(shí),該樣品抗拉強(qiáng)度為1272.5 MPa;試驗(yàn)溫度為550℃時(shí),該樣品硬度值為402.5 HV。試樣斷口分布有大量的韌窩和很少的準(zhǔn)解理形貌,表明模具鋼有較高的強(qiáng)度和韌性。
[Abstract]:The steel samples of hot work die were designed and prepared by adding elements such as Cr-Mo-Mo-NiNI-WGV and so on.The effect of heat treatment on the properties of hot working die steel was studied.The results show that the properties of die steel after quenching and tempering at 1: 1025 鈩，
