Abstract
This invention relates to a method for processing Cu-Zn-Al shape-memory alloy billet. The method comprises: removing the oxide layer from the Cu-Zn-Al shape-memory alloy billet, forging at 600-800 deg.C, rolling at 550-750 deg.C, annealing at 600-720 deg.C during rolling, stretching at 460-650 deg.C, and annealing at 600-690 deg.C. The final size after forging is 45 mmX45 mmX1000 mm. The obtained Cu-Zn-Al shape-memory alloy billet can be stretched into wires with different diameters according to different requirements, which can be used to produce spectacle frames with excellent elasticity.
Description
Technical field
The present invention relates to the shape memory alloy technical field, particularly a kind of working method of blank of shape memory alloy of cupper, zinc, and aluminum is applicable to manufactured copper zinc-aluminum shape memory alloy frame.
Background technology
In glasses industry, utilize the super-elasticity of shape memory alloy, make frame, make frame indeformable, guarantee user's aesthetic property of glasses in use, this frame of making of shape memory alloy wire material is constantly development at home and abroad at present.
What use at present is niti-shaped memorial alloy, compares with the frame that niti-shaped memorial alloy is made, and making frame with copper-zinc-aluminum shape memory alloy silk material has following advantage:
1, cost is low, and the material cost of copper-zinc-aluminum shape memory alloy is 1/4th of a niti-shaped memorial alloy.
2, the processing characteristics of copper-zinc-aluminum shape memory alloy is better than Ultimum Ti, particularly hot workability greatly, and niti-shaped memorial alloy is more incomparable, in hot procedure brittle failure can take place such as niti-shaped memorial alloy.Copper-zinc-aluminum shape memory alloy yield rate in the course of processing is more much higher than niti-shaped memorial alloy.
3, niti-shaped memorial alloy can't weld, and simultaneously hot workability is also relatively poor, repeatedly be shaped, and therefore repeatedly annealing can't make the plant kind of style of multiplex (MUX) more.Copper-zinc-aluminum shape memory alloy can weld, because hot workability is good, can once-forming, and can make complicated shape simultaneously.
The present invention is directed to this problem, developed a kind of working method of blank of shape memory alloy of cupper, zinc, and aluminum.
Summary of the invention
Purpose of the present invention provides a kind of working method of blank of shape memory alloy of cupper, zinc, and aluminum.
The concrete technical scheme of the present invention is the copper-zinc-aluminum shape memory alloy corynebacterium blank that has prepared to be carried out deep processing, to satisfy the requirement of making frame.It is characterized in that: with the blank of shape memory alloy of cupper, zinc, and aluminum scale removal, forge, forging temperature is 600 ℃-800 ℃, rolling temperature is 750 ℃-550 ℃, to carry out anneal in the operation of rolling, the optimum temps of anneal is 600 ℃-720 ℃, and the forging final size is 45mm * 45mm * 1000mm; The tensile deformation temperature is 460 ℃-650 ℃, and carrying out the anneal temperature after the stretching is 600 ℃-690 ℃.The same common process of other step.
Above-mentioned working method, forging temperature is preferably 640 ℃-800 ℃, and rolling temperature is preferably 580 ℃-720 ℃, and the anneal temperature is preferably 660 ℃-700 ℃ in the operation of rolling, the tensile deformation temperature is preferably 480 ℃-630 ℃, and carrying out the anneal temperature after the stretching outstanding is 650 ℃-680 ℃.
After adopting the inventive method to blank of shape memory alloy of cupper, zinc, and aluminum processing, can require to be drawn into the silk material of different diameter according to reality, be used to make frame, its product shows good superelastic properties.
