continuous cooling transformation curve

基本解释

The expanding curves and continuous cooling transformation curve (dynamic CCT curve) of X60 pipeline steel were obtained by dilatometry and microscopic test under different cooling speed.
利用膨胀法，结合金相法，测定了X60不同冷却速度下连续冷却转变的膨胀曲线，获得了该钢的连续冷却转变曲线（动态CCT曲线）；
The continuous cooling transformation(CCT) curve was constructed chiefly by means of dilatometry, and combined with metallography to exact fix on the phase transition points of different cooling rate.
连续冷却转变（CCT）曲线的建立主要应用膨胀法，并辅助以金相分析法来精确分析不同工艺条件下的相变点。
