Abstract :
The process of gradual damage accumulation under alternating stresses resulting in changes of the properties, phase structure, and defect substructure of the material and in the initiation of cracks, their further growth, and finally failure of the material is called the metal fatigue. The application of modern structural methods of research has allowed making the certain steps in understanding of the nature of fatigue failure of metals and alloys. The transmission electron microscopy was used to analyze formation of the structural phase states in the fatigue crack growth area in 08X18H10T austenite (0.1% C; 17.5% Cr; 10% N; 1% Ti) and annealed (ferrite-perlite structure) and quenched (martensite) (0.6% C, 1% Mn, 2% Si) stainless steels subjected to high-cycle fatigue.
