Abstract The Ti_1－xNi_x(x=45%—49.8%) (atom fraction) shape memory alloy (SMA) ribbons were fabricated by melt spinning process. Effect of Ni content on transformation behavior of as-cast and 450 ℃, 500 ℃ annealed TiNi SMA ribbons were investigated by differential scanning calorimetry. The results showed that the A→M/M →A one-stage martensitic transformation occurs upon cooling and heating in as-cast and annealed Ti_1－xNi_x(x=45%—49%)SMA ribbons. When Ni content is 49.8%, the A→R→M two-stage martensitic transformation occurs upon cooling, and M→A one-stage martensitic transformation occurs upon hea-ting in as-cast and annealed TiNi SMA ribbons. With the increasing Ni content, the temperature range of martensitic transformation upon cooling and reverse martensitic transformation upon heating in TiNi SMA ribbons widens first and then narrows, and reaches the maximum when Ni content is 48%. The martensitic transformation temperature range in the annealed alloy ribbons is narrower than that in as-cast TiNi SMA ribbons. With increasing Ni content, the martensitic and reverse martensitic transformation temperature and temperature hysteresis of TiNi SMA ribbons increase. When Ni content is 49%, the martensitic transformation temperature of SMA ribbons reaches the maximum. When Ni content is 49.8%, the martensitic transformation temperature decreases drastically.
