It was found that under the influence of experimental factors, significant change of the dislocation structure of investigated alloys occurs. However, their strength characteristics are practically unchanged, but the elongation of rib №2 area is 1.3 times reduced compared to the rib of № 14 area for the Д16ATНВ alloy and 1.8 times - for the В95T1 alloy. The fatigue crack growth resistance of alloys changes similar, especially the fatigue threshold, it is reduced 1.5 and 1.6 times for the Д16ATНВ and В95T1 alloys respectively. It is shown that the alloy the type В95 is more liable to degradation during long-term operation in comparison with the Д16 alloy.
