Experimental study of the Er308LSI steel acoustic properties
Annotation
The experimental results on the acoustic properties (the ultrasound velocity and attenuation coefficient) and the relative thermal expansion of the Er308LSI steel within the temperature range of $20$–$1100^{\circ}$C are presented. Application of the dilatometer studies makes it possible to improve the accuracy of the experimental data on the acoustic properties and to calculate the temperature dependency of the steel density as well as of the Young modulus. The temperature dependencies and calculate the approximating equations for the investigated and the calculated properties of the steel are plotted.
