Abstract
We present experimental study results of the ultrasound velocity, the relative thermal expansion (within 20–1000°C) and the microhardness (within 20–500°C) of 09Mn2Si 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.
