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