We report measurements of the attenuation of longitudinal elastic waves, carried out using a broad-band immersion pulse-echo technique. The ultrasonic attenuation has been measured as a function of temperature and frequency during the martensitic transformation of monocrystalline and polycrystalline Cu-Zn-Al alloys. It has been shown that the most likely mechanism producing ultrasonic attenuation is the scattering of the ultrasonic waves by regions with different acoustic impedances. |
