Abstract

A systematic study was carried out to understand the various microstructural changes in the heat-affected zone due to laser treatment on 2.25Cr-1Mo steel. The observed microstructures pertain to different cooling rates at different depths from the surface. A good correlation of the microstructures with the corresponding time-temperature-transformation (TTT) diagram of the steel was observed.
