Abstract
The acoustic properties (ultrasound velocity, attenuation coefficient) and the relative elongation of U8 steel are studied in the temperature range 20–1050°C and its microhardness is studied in the range 20‒500°C. The measured relative elongation can improve the accuracy of determining the ultrasound velocity and the attenuation coefficient and can be used to calculate the temperature dependences of the density and Young’s modulus of the steel. Approximating equations for the temperature dependences of the experimental and calculated mechanical and thermophysical properties of the steel are derived.
