Abstract
Variation of the structure and mechanical properties of alloy 36NTYu after various kinds of treatment (quenching with aging at 750°C, deformation with degree e = 50 – 98%, annealing at 750°C) studied by mechanical tensile and fatigue tests is described. The changes in the dislocation structure and lamellar segregations of γ′-phase in the treatment process are determined. It is shown that the fatigue limit and the friction stress are well correlated.
