The shape memory properties and microstructure of the as-received and aged polycrystalline Ni45,3Ti29,7Hf20Pd5 shape memory alloys were investigated. It was revealed that their functional properties such as transformation temperatures, thermal hysteresis, dissipation energies strongly depend on thermal cycling, aging treatments and martensite morphology. Transformation temperatures decreased substantially with thermal cycling while thermal hysteresis and dissipation energies were closely linked to precipitate characteristics and only weakly affected by cycling.
