Anotace
The project addresses the issue of resistance of turbochargers' radial wheels against thermomechanical stress. To obtain this data, we initiate completely unique research, leading to the determination of the thermomechanical resistance interaction of the used nickel superalloys, in connection with the setting of the technological process of precision casting (the resulting structure, the mechanical properties of the casting).
