| Abstract: | By jointly using expansion method and metallographic method,the expansion curves of continuous cooling transformation at different cooling rates has been determined for X65 pipeline steel on Gleeble-1 500 hot simulation testing machine,thus the continuous cooling transformation curve(dynamic CCT curve)of the same steel grade has been obtained as well.The austenite transformation process in the course of continuous cooling transformation of X65 pipeline steel and the structure of its product have also been studied.The frame of reference for establishing controlled rolling and controlled cooling process at the site is available by analyzing the curves. |
