The elastocaloric effect in an amorphous and crystalline Ti2NiCu alloy was studied. On the basis of the data obtained, the amorphous and crystalline alloys were compared, and the specific power of the samples was estimated. An IR thermography technique was developed and applied to determine the kinetics of the process. The practical application of this alloy to alternative energy systems is discussed.
