摘要：
Ti-46Ni alloy ribbons were fabricated by melt-spinning. The microstructure characteristics, the transformation behaviors and shape memory effect of the Ti-46Ni alloy ribbons were investigated by SEM, XRD, differential scanning calorimetry and bending test. The results show that the microstructure morphologies of as-cast and 400 similar to 600 degrees C annealed Ti-46Ni alloy ribbons are dendritic, the grain is small, and the composition phases are martensite (B19') and parent phase (B2). The one stage martensite transformation appears upon cooling and heating. The as-cast and annealed Ti-46Ni alloy ribbons are both of excellent shape memory effect.
