Theoretical cooling curves, the relationship between cooling curve, fraction of solid and liberation of latent heat per unit time, and experimental results are presented.
给出了理论冷却曲线、冷却曲线、固相率及单位时间内潜热释放速度之间的关系及实验结果。

The transformed ferrite volume fraction increases and grain size decreases with the increase of cooling rate.
随着冷却速率的增加，铁素体体积分数减少，晶粒尺寸变细。
3
The results show that with the increase of cooling rate, the grain size of proeutectoid ferrite decreases, the volume fraction of proeutectoid ferrite and acicular ferrite increases.
