| 摘 要： | 研究了0～1.5％Nb对25 kg真空感应炉冶炼的W3M02Cr4V钢(％:0.8～1.1C、3.8～4.1Cr、2.9～3.2W、1.8～2.1Mo、1.0～1.3V)组织和力学性能的影响。试验结果表明:随着Nb含量提高,铸态组织中铌碳化物增多;淬火奥氏体晶粒变细;1180℃淬火时,1.2％～1.5％Nb钢比≤0.1％Nb钢HRC值提高了6.0;二次硬化能力和红硬性也得到了提高;使钢在较高淬火温度下的机械性能得到改善。

| Abstract: | The effect of0～1.5% Nb on structure and mechanical properties of steel W3Mo2Cr4V(0.8~1. 1C,3.8 ~4. 1Cr,2.9~3.2W,1.8~2. 1Mo,1.0~1.3V)melted by 25 kg vacuum induction funace has been studied. Test results showed that with increasing Nb content the amount of niobium carbide in cast structure increased; quenching austenite grain was refined; as quenched at 1180 ℃,compared with HRC value of≤0. 1% Nb steel the HRC value of 1.2%~ 1.5%Nb steel increased by 6.0; the secondary hardening ability and red hardness of Nb steel were obviously increased. |
