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).
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_v^(O.46) × C_r^(-0.26) are constructed and obtained.
