Correlation between Mechanical and Acoustic Properties of Deformable Metals

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
