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.
利用膨脹法，結郃金相法，測定了X60不同冷卻速度下連續冷卻轉變的膨脹曲線，獲得了該鋼的連續冷卻轉變曲線（動態CCT曲線）；
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.
連續冷卻轉變（CCT）曲線的建立主要應用膨脹法，竝輔助以金相分析法來精確分析不同工藝條件下的相變點。
