Stabilization of the B19 martensite by rapid solidification in a Ti-45Ni-5Cu (at.%) alloy has been investigated by means of differential scanning calorimetry and transmission electron microscopy. Rapid solidification process induced the B2-B19 transformation prior to formation of the B19 martensite,

β¦ Synopsis
Melt spinning of TisoNiso_~ Cu x (x = 10, 25, 40) alloys showed that the glass-forming ability is good for Cu-rich compositions and poor for Ni-rich compositions. The results of mechanical alloying experiments in the same system showed a reverse trend as far as the glass-forming ability is concerned. These contradictory results are explained in the light of thermodynamic and kinetic considerations. Crystallization results of the melt spun alloys are also presented.
