Conclusions
-
1.
It has been established that SPD reduces inelastic strain per cycle for the stress levels studied with any number of loading cycles.
-
2.
As a result of mechanical strengthening the fatigue limit and endurance of steel 14Kh17N2 specimens increased to a greater extent than for steel 20.
