3. Influence of rail chemical composition
The influence of chemical composition on the TRC (continuous cooling transformation) curve was described in the article "Rails de chemins de fer. Aspects métallurgiques"
Some high-alloy grades may require heavy-duty postheating after welding to reduce the cooling rate, which has the disadvantage of enlarging the heat-affected zone (HAZ).
