By simulating welding and simulating heat treatment after welding, CCT Curves of UIC900A and U75V rail steels are determined by the expansion method.

模拟钢轨焊接及焊后热处理工况，采用热膨胀方法分别测定uic 900a及u75 V钢轨钢的连续冷转变曲线(CCT曲线)。

The CCT curves of part austenitic and complete austenitic show the similar shape, but the former shifts upward and left compared with the latter, and the upward is more obvious.

部分奥氏体化CCT曲线与完全奥氏体化CCT曲线形状相似，但前者相对于后者普遍上移和左移，且上移比较明显。
