Abstract:

The Ti-46Ni alloy ribbons were fabricated by melt-spinning. The microstructure characteristics, the transformation behaviors and shape memory effect of Ti-46Ni alloy ribbon were investigated by SEM, XRD, differential scanning calorimetry and bending test. The results show that the microstructure morphology of as-cast and 400~600℃ annealed state of Ti-46Ni alloy ribbon presents dendritic, the grain is small, and the composition phases are martensite (B19ˊ) and parent phase (B2). The one stage martensite transformation are appeared upon cooling and heating. The as-cast and annealed Ti-46Ni alloy ribbons are all of excellent shape memory effect.
