Abstract
The analysis of the service conditions of nuclear power constructions in case of low-cycle fatigue showed, that appearance of macrocrack is inadmissible. The conditions of safe operation require collecting of reliable information about material’s state at the stage of damage accumulation of dispersed microcracks. It was found that a change of the structure, physical and mechanical properties of specimen of steel 08Cr18Ni10Тi leads to changes of elastic waves parameters. The authors suggested diagnostic parameter defi nable by the time of propagation of elastic waves, that makes possible to estimate material state of supervised construction. The proposed criterion can be used for measuring on real objects that are exploited in low-cycle fatigue.
