摘　　要：利用热力学软件Thermo-calc计算了含钒高速铁路车轮钢中第二相的析出行为,详细分析了低碳车轮钢中平衡相的组成以及温度和钒含量对第二相析出的影响。结果表明,钢中钒含量的变化对车轮钢中第二相析出量有较大影响,对第二相析出的温度几乎无影响;温度变化对钢中稳定存在的第二相析出产物影响较小,对瞬态析出相的影响较大。A thermodynamic Thermo-calc software was used to calculate the precipitation behavior of second phase in vanadium-bearing high-speed railway wheel steel.The composition of equilibrium phase in low-carbon wheel steel and the influence of temperature and vanadium content on the precipitation of the second phase were analyzed in detail.The results show that variation of vanadium content in steel has a great influence on the second phase precipitation in wheel steel,and almost no effect has been observed on the precipitated temperature of the second phase.The temperature variation has small effect on the stable second phase precipitated products in steel,but has great effect on the transient precipitated phase.
