Microstructure Modelling for Phase Transformation in Low Carbon Steel

摘要: 通过定量金相的方法研究了连续冷却过程中低碳钢的相变组织,在分析研究相变影响组织因素的基础上,构造了低碳钢的相变动力学模型X=1-exp(-0.642t^0.086),以及相变后的铁素体晶粒尺寸模型D_α=5.7×D_γ^0.46×C_r^-0.26。

Abstract: The microstructures of phase transformation by using quntitative metallogra phy was studied. On the basis of analyzing the effects on the microstructures of phase transformation the model of transformation kinetics X=1-exp(-0.642t^0.086), and the model of ferrite grain size D_α=5.7×D_γ^0.46×C_r^-0.26 are constructed and obtained.
