The two-stage reversible transformation ADRDM (A-parent phase, R-R phase, M-martensite) occurred upon heating D cooling in 350-550℃ annealed Ti-50.8Ni alloy. With increasing annealing temperature, the R, M transformation temperature TR, TM of the alloy are first increase then decrease; the M transformation temperature hysteresis ΔTM decreases continuously; the R transformation temperature hysteresis ΔTR is constant. After adding 0.5%V, the transformation type and ΔTR,ΔTM of the alloy do nearly not change, while the TR, TM decrease. After adding 0.3%Cr, the transformation type and ΔTR of the alloy do nearly not change; the ΔTM increases; the TR, TM decrease greatly. The superelastic stress and strain of 400℃ annealed Ti-50.8Ni alloy are 473MPa and 6.4%, respectively. After adding 0.3%Cr, the superelastic stress of the alloy increases, reaches 620 MPa, and the superelastic strain decreases, reaches 3.5%. After adding 0.5%V, the superelastic stress and strain decrease, and reach 388 MPa and 4.9%, respectively. When annealing temperature increases from 400℃ to 500℃, the superelastic stresses of three alloys are all decrease.
