Radiation nondestructive testing of structural modifications of hard alloys after cryogenic treatment

The processes that proceed in hard alloys under the action of ionizing radiation were studied after cryogenic treatment. Acoustic emission due to the liberation of the energy stored in a lattice was shown to occur upon the irradiation of hard alloys. The nondestructive testing of hard alloys was shown to allow the prediction of the life and behavior of a drilling tool under different types of treatment.
