A method for producing a Ti-Ni based functionally graded alloy comprises cold working a Ti-Ni based alloy, and annealing the cold worked Ti-Ni based alloy under a temperature gradient to impart a graded function to the Ti-Ni based alloy. The Ti-Ni based alloy is cold worked to a ratio of 25 to 65%, and the cold worked Ti-Ni based alloy is annealed under a temperature gradient of 823 to 466 deg.K. A Ti-Ni based functionally graded alloy produced by the method is proportionally controllable, wherein a strain recovery rate of the Ti-Ni based functionally graded alloy is reduced to 1/30 to 1/100.
