Microstructure Modelling for Phase Transformation in Low Carbon Steel

摘要: 通過定量金相的方法研究了連續冷卻過程中低碳鋼的相變組織,在分析研究相變影響組織因素的基礎上,構造了低碳鋼的相變動力學模型X=1-exp(-0.642t^0.086),以及相變后的鐵素體晶粒尺寸模型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.
