摘　　要：以含Mo低合金钢为对象,利用计算机仿真技术,建立热处理过程中碳氮化物析出行为热力学模型,采用Thermo-Calc软件模拟微合金元素的变化规律。结果表明,Mo元素可以显著地提高复合碳氮化物的析出温度,降低间隙元素和微合金元素的活度,所建立的热力学模型准确度较高。The carbonitride precipitation behavior in containing Mo low alloy steel were studied by computer simulation and Thermo-Calc software simulation. The results show that the precipitation temperature of carbonitride is improved due to adding Mo, while the activity of interstitial element and microalloy elements are reduced. The thermodynamic model shows good accuracy.
