Investigation of acoustic properties of Russian grade 1Cr18Ni10Ti steel

This article presents results of experimental study of the acoustic properties (speed and coefficient of attenuation of ultrasound) and relative temperature expansion of Russian grade 1Cr18Ni10Ti steel in the temperature range of $20$–$1100^{\circ}$C. The approximating equations for temperature dependences between experimental and calculated thermophysical and mechanical properties of steel are obtained.
