Abstract
Two ultrasonic attenuation maxima with two corresponding minima of longitudinal sound velocity and two internal friction peaks have been measured in NiTi (Fe) alloy on cooling at about -26°C and -90°C respectively. EM observation shows the maximum at -26°C is associated with the normal-incommesurate transition whereas that at -90°C is due to lock-in transition. The mechanism of the internal friction associated with N/I transition is centered on.
