The ultrasonic wave reflection method has been used to determine the elastic constants of various steels at the temperature range from room temperature to -196°C. Liquid nitrogen was used as a cooling agent. The data of the temperature dependence of elastic moduli for commercial alloys and steels were given in tables with their chemical compositions. Moreover, the data were represented by the empirical formulae in the form of exponential function of temperature.
From the results, it can be concluded that both moduli (E, G) tend to increase with decreasing temperature.
