| Abstract: | This paper has studied the weldability of U71 Mn and 74SiMnV rail steels for flash butt welding process. By means of Gleeble simulation technique ,the continuous cooling transformation behavior of U71 Mn and 74SiMnV rail steels has been investigated , and the mechanical properties of simulated HAZ (coarse grained region ) have been measured. The effect of cooling rate and chemical composition on weldability have been analyzed. A comparison has been made among them and other five foreign rail steels. |
