Conclusions
The scattering of fatigue data for alloys D1, D16, and AV depends on: a) heterogeneity of the chemical composition; b) the difference in changes in mechanical properties of the alloys during fatigue tests of individual samples or parts; c) the difference in the average hardness of individual samples or parts (the effect of this factor increasing with the amplitude of the cycle); d) the extent of branching during propagation of the fatigue crack.
