Abstract

In the present study we investigate the effect of ultrasonic treatment on the functional properties of Ti-50.4at.%Ni alloy. It is shown that the shape memory effect and its realization peculiarities depend on the parameters and conditions of ultrasonic influence. Ultrasonic treatment of a preliminary deformed TiNi alloy in a fixed state promotes reduction of strain recovery at subsequent heating through the temperature interval of the reverse martensite transformation, i. e. some locking of the induced strain occurs during the ultrasonic treatment of material in a fixed state. In the samples after ultrasonic treatment, the extension of shape recovery temperature range during the first thermal cycle, as well as the temperature dependence of strain recovery kinetics on the ultrasonic power have been observed.
