Conclusions
-
1.
The superposition of ultrasonic vibrations during the compression and tensioning of difficult-to-deform materials contributes to a reduction in their resistance to plastic deformation, yield points, and strength.
-
2.
The effect of ultrasound during the tensioning of difficult-to-deform materials is accompanied by a reduction in the limiting plastic deformations as a result of the formation of additional damage to the crystal structure.
-
3.
The effectiveness of ultrasound on the mechanical properties of difficult-to-work materials is determined by their chemical composition and structure, as well as by the parameters of the ultrasound and the temperature of the tests.
