FIELD: determination of cyclic strength of structures from austenitic and austenitic- ferritic steels. SUBSTANCE: tested metal is cyclically loaded in local zone of structure with the use of indenter and local magnetization and measurement of magnetization are simultaneously conducted in zone of action of indenter. In process of test dependence " impression effort-magnetization " is recorded by which change degree of damage to metal is evaluated. EFFECT: simple and efficient test of safe fatigue life of metal at various stages of usage of structure.
