Abstract
1. The method described in this study for constructing the line depicting the beginning of formation of a macroscopic crack from the increase in low-amplitude energy dissipation due to cyclic loading makes it possible to determine an important parameter of structural strength-residual life. 2. The vibration resistance of chromium-nickel stainless steels depends considerably on the phase composition. The steel with a martensitic structure had the lowest vibration resistance due to its low capacity to absorb energy in irreversible processes during its deformation. The two-phase steel with austenite which was metastable during deformation was characterized by high vibration resistance due to a successful combination of fatigue and damping properties. The chromium-nickel steel with unstable austenite was intermediate between the martensitic and austenitic-martensitic steels with regard to vibration resistance due to its low endurance limit, even though it has the highest damping capacity.
