Heat treatment as a method of restoring of the material 15Cr12WNiMoV after operational processes
Institute of Mechanical Engineering Problems of the Russian Academy of Sciences (IPM of RAS) - branch of the FIC of the Institute of Applied Physics of the Russian Academy of Sciences, 603024, Nizhny Novgorod, Russia
The article presents the results of studies of the post-operational state of the turbine rotor blade material of the power plant (operating time is about 30000 hours). High-temperature fatigue processes occurring in the heat-resistant steel 15Cr12WNiМoV have been studied. These processes manifested themselves in changing microstructure and mechanical characteristics. Various heat treatment modes were tested to regenerate the structure and restore the mechanical properties of the alloy in order to develop the scientific foundations of the resource-saving technology of turbine blades.
