Abstract In this work, correlations between ultrasonic speed, strength, and plasticity are studied in Fe – 18 wt % Cr – 10 wt% Ni alloy under uniaxial tension. Special attention is paid to the effect of static loading on acoustic characteristics and destruction parameters of alloy. To provide non-destructive testing of structural state and mechanical parameters of the material under consideration, its acoustic and mechanical properties are finally studied in a temperature range of 180 K ≤ T ≤ 318 K © 2022 The Authors.

Keywords: non-destructive testing, acoustic parameters, ultrasound velocity, temperature dependence, Fe-Ni-Cr alloys. 1. Introduction The safety of many critical facilities in the nuclear power industry, aviation, shipbuilding, and oil and gas industries is greatly influenced by the resource exhaustion of structural elements of equipment during the operation of structural materials. Hence, detecting the pre-defect state of the material, controlling its physical and mechanical properties to prevent any continuity violations, as well as assessing the real technical condition of the responsible structural elements via non-destructive testing tools has become a hot topic.
