The TiNiHf alloys are newly developed as high temperature shape memory alloys with the high transformation temperatures and with lower cost in comparison with TiNiX (X = Pd, Pt) alloys. Until now, no results about the effects of aging at high temperature (above 953K) in the TiNiHf alloys are reported. The purpose of the present work is to investigate the microstructure, transformation temperature, mechanical properties and shape memory effects (SMEs) for Ti{sub 36}Ni{sub 49}Hf{sub 15} alloy aged at 973K for different hours by transmission electron microscopy (TEM), X-ray diffraction (XRD) techniques, electrical resistance-temperature measurement, bending and tensile tests.
