A comparative study of functional properties of Hustler alloys Ni-Mn-Ga was performed. The thermomechanical properties of low-temperature Ni53.8Mn20.0Ga24.3Si1.7 and high-temperature Ni56,2Mn18.8Ga23.2Si1.8 alloys were measured. The alloy that demonstrate phase transformation above room temperature (high-temperature) possess lower critical stress 250 MPa, but higher recoverable deformation 2,2 %. Both alloys demonstrates II type thermoelastic phase transformation.
