Conclusions 1. In the tension of molybdenum with the application of ultrasonic vibrations the general rules of strain hardening according to a multistage plan are observed, but under the influence of the ultrasonic vibrations the stage of parabolic hardening with a tangle type dislocation structure is significantly broadened within the studied range of amplitudes and a later transition to the stage of formation of the dislocation cell structure is noted. 2. The relationship of the parameters of strain hardening and of the dimensions of the cell structure to the amplitude of the ultrasonic vibrations have a complex inconsistent structure caused by the simultaneous action of competing mechanisms of softening (the ultrasonic vibrations reduce the resistance to dislocation movement) and hardening (ultrasonic vibrations of larger amplitude cause the generation of new additional dislocations).
