Abstract:
The work presents the results of an experimental study on the core speed of ultrasound, the relative thermal expansion, the densities, and the Young's modulus calculated based on these data for several hardened and annealed steels in a wide temperature range. The experimental data were processed by the leastsquares method, which made it possible to obtain approximating equations for the temperature dependences of the studied and calculated properties of steels.
