Abstract
In order to formulate and optimize the pre-bend process for heavy rails for high-speed train systems, cooling experiments and microstructure observations were conducted to determine the appropriate cooling rate. Also, the rules of bending during the cooling process were studied by the thermo-mechanical coupled finite element method (FEM). Based on the simulation results, the shape change, temperature change, and solid-state phase transformation in different areas of the rail during the entire cooling process were investigated. The obtained results can explain the occurrence of the bending process, which has great scientific and practical significance for rail production.
