Study of the Influence of Residual Stresses on the Fatigue Strength of Samples Made of Titanium and Nickel Alloys

In this paper, we compare the results of measurements of residual stresses and study the influence of residual stresses on the fatigue strength of samples made of titanium and nickel alloys after various types of treatment: turning with the use of various lubricating-cooling tools, grinding, and surface plastic strain operation.
