Experimental study of acoustic properties and microhardness of $09\rm Mn2\rm Si$ steel

We present experimental study results of the ultrasound velocity, the relative thermal expansion (within $20$–$1000^{\circ}$C) and the microhardness (within $20$–$500^{\circ}$C) of $09\rm Mn2\rm Si$ steel. From the experimental data, we calculate density and Young modulus values. We treated the hardened and the annealed specimens. The mean-square processing of the experimental results makes it possible to obtain the approximating equations of the temperature dependences of the studied and the calculated steel properties.
