| Abstract: | The microstructure and the properties of the rail-head were compared and analyzed after being carried out three kinds of heat treatment process, heating and still air-cooling, heating and wind cooling, quenching and tempering. The results show that the process of heating and wind cooling for the rail-head is feasible and the microstructure and properties of the treated rail-head can satisfied the standard. |
