Modeling of Ultrasonic Initiation of Shape Memory Effect

摘要

Modeling of ultrasonic initiation for alloys with shape memory effect is carried out. The ultrasonic heating process is described taking into the account the temperature dependence of the studied material properties. Research process of heat generation for the TiNi samples under the ultrasonic influence shows that the treatment of the material under the localized acoustic influence causes the constant temperature distribution along the sample. It is possible to control the phase transformation in the material, the speed of its implementation by varying the frequency and amplitude of the ultrasonic vibrations during the phase transition. The aim of this study is the modelling heating of alloys with shape memory effect under ultrasonic action at several resonance frequencies.
