  • Microstructure development of creep resistant ferritic ...

    15Mo3 type creep resistant steel samples were crept at 550 °C for different lifetimes. The effect of the damage on the microstructure of the steel was investigated by different techniques, including TEM and EBSD methods. Results show that after a certain time the grain orientation spread and average misorientation increase and then decrease.
