摘要
利用扩散动力学理论、Thermo-Calc、Dictra等仿真软件数据库,建立热处理过程中GH4169合金钢Laves相回溶规律的数学模型,研究热处理回溶过程Laves相的溶解度与冷却速度和温度间的关系。结果表明,基于GH4169合金钢的Laves相回溶规律数学模型的预测结果与实际试验结果基本相似,拟合曲线近似满足指数变化规律。
Using diffusion kinetics theory, thermo-Calc, dictra and other advanced simulation software database, a mathematical model was established to study the re-dissolution behavior of Laves phase in GH4169 alloy steels, understand the relationship between the dissolution rate, cooling rate of Laves phase and temperatures. The results show that the mathematic model has high fitting with real experimental data, and the fitted curve has exponential relationship.
