Titanium nickelide powder magnetic susceptibility

Magnetic susceptibility measurements have been used to determine the martensitic transformation characteristics in porous titanium nickelide. It has been established that the magnetic susceptibility of porous titanium nickelide is temperature dependent, and is a superimposition of the orientational paramagnetism due to the impurities in the oxygen containing phases combined with the hysteresis loop caused by the martensitic transformation. Deformation of porous titanium nickelide produces a significant increase in magnetic susceptibility that is partially eliminated by annealing.
