Assessment of reheat cracking susceptibility in Cr-Mo-V turbine rotor steel
Miscellaneous
·
OSTI ID:5768430
The evaluations of reheat cracking susceptibility in CrMoV turbine rotor steel were performed using a commercial weldment and thermally simulated heat affected zones (HAZ). The examinations were carried out in terms of a thermal cyclic test and Charpy type three point notch opening bend test. In addition, a mechanical and microstructural characterization was conducted on the commercial weldment to examine the joint strength and its microstructural stability after high temperature exposure.
