Resonant ultrasound spectroscopy (RUS) was used to study the elastic mechanical properties and internal friction of two wrought magnesium alloys, AZ31B and ZK60, from 25°C to 450°C. Samples in the rolled, transverse and normal directions were characterized at 50°C intervals to determine the temperature dependency of elastic moduli and stiffnesses for each direction. The temperature dependencies represented as, dE/dT, dG/dT, dB/dT, dC11/dT, dC12/dT, and dC44/dT are provided herein. To evaluate the RUS technique for this type of alloys, Young’s modulus was also determined by conventional static tension testing and the results were compared. From the same RUS experiment, the internal friction variation with temperature was calculated for both alloys. The coefficient of thermal expansion for each direction over the temperature range considered were determined, as they were needed to simulate the RUS spectra. This study shows that RUS can be a convenient and accurate technique to supply quantitative elastic mechanical data and fill the existing gaps on light metals characterization.
