Abstract

The invention discloses a preparation method of an elastic memory alloy material for a spectacle frame. The alloy material can comprise the following chemical components in percentage by weight: 10-12% of Zr, 6-8% of Nb, 11-13% of Al, 4-6% of Cu, 5-7% of Mg, 2-4% of Zn, 1-2% of Ag, 0.5-1.5% of Ce, no less than 0.05% of O, no less than 0.01% of N, no less than 0.02% of H and the balance of Ti and inevitable impurities; and the preparation method comprises the following steps: (1), melting and casting; (2), hot rolling: heating a continuous casting blank to about 980-1020 DEG C, preserving the heat of the continuous casting blank for about 15-25 minutes, and then rolling the continuous casting blank and obtaining a 10X10 mm wire after rolling, wherein the final rolling temperature is substantially 860 DEG C; (3), cold pulling; and (4), heat treatment: heating the cold-pulled material to about 260-280 DEG C and preserving the heat of the cold-pulled material for 4-6 minutes.

Description

technical field [0001] The invention relates to the technical field of alloy materials, in particular to a method for preparing an elastic memory alloy material for spectacle frames. Background technique [0002] The traditional spectacle frame material uses BZN15-20, which is widely used in spectacle manufacturing because of its excellent craftsmanship and performance, but its nickel content is as high as 13.5-16.5%, which increases the cost. In order to reduce the cost, CN101967580A A lens construction material is disclosed which has reduced nickel content to 7-9%. However, because Ni element can cause allergic reaction and carcinogenicity to some people, the above-mentioned patent application still containing nickel element cannot overcome this problem. [0003] In addition, the existing spectacle frame materials are simple in composition and poor in corrosion resistance. After a general spectacle frame is used for 3-6 months, it will become old and black due to the corr...
