Abstract
The present invention relates to a method for preparing a for titanium-nickel composite yarn material for a spectacle frame. In the preparation process, titanium-nickel thermometals are overlapped and combined in the mode of explosion or extrusion, and composite bar stocks of the titanium-nickel thermometals are obtained; the composite bar stocks of the titanium-nickel thermometals are processed on a universal rolling mill in the mode of cold cogging, and then are processed in the mode of drawing. The processing rate of each pass is from 5% to 10%, and the total processing rate is less than 70%; finally, heat treatment is carried out under the vacuum condition of 10<-2>Pa. The annealing temperature is controlled to be from 300 DEG C to 650 DEG C, and the temperature is kept for 30 minutes to 120 minutes. The preparation method of the present invention improves the strength intensity of a titanium-nickel combination layer and satisfies the requirement for manufacturing the high-grade spectacle frame.
