Description
Technical field
The present invention relates to technical field of alloy material, particularly a kind of preparation method of Elastic memory alloy material for spectacle frame.
Background technology
Conventional spectacle frames material adopts BZN15-20, this material because having more excellent technique and use properties in glasses manufacture large usage quantity, but because its nickel content is up to 13.5-16.5%, and cost is increased, in order to reduce costs, CN101967580A discloses a kind of Glasses structure material, which reduces the content of nickel to 7-9%.But can produce anaphylaxis due to Ni element to part population and have carinogenicity, the above-mentioned patent application therefore still containing nickel element can not overcome this problem.
In addition, existing this kind of frame material composition is simple, corrosion-resistant, after general frame uses 3-6 each moon, due to the corrosion of frame metal material surface, cause it to send out old, send out crow, not only affect the attractive in appearance of glasses, also can impact HUMAN HEALTH; The rigidity of material that uses of frame is comparatively large in addition, once glasses are subject to external force, and gently then frame damage itself, heavy then stab glasses.
In order to overcome the problems referred to above, the frame of the pure titanium and its alloys of routine has been developed, although titanium alloy has good solidity to corrosion, as disclosed a kind of titanium alloy frame material in prior art in prior art, its chemical composition is by weight percentage: zirconium 20-40%, hafnium 0.5-3%, tantalum 0-2%, oxygen 0.05-0.2%, carbon 0-0.15%, nitrogen 0-0.01%, hydrogen 0-0.02%, surplus is titanium.But titanium material processing difficulties, the cost of material is higher, limits the application of titanium alloy in frame; And the Young's modulus of this titanium alloy frame frame is less than 75GPa, and rigidity is little, is easily out of shape, wear rear easily lax.
In order to overcome the above-mentioned defect of titanium alloy frame, CN102051533A discloses a kind of zirconium-base amorphous alloy, spectacle frame and manufacture method thereof, and it contains the copper of 10-15%, the nickel of 7-13%, the niobium of 5-8.0%, the aluminium of 2.0-6.0%, all the other are zirconium and inevitable impurity.The Young's modulus of frame prepared by this patent application is higher, but still has nickel element in its composition, still there is the above-mentioned problem mentioned; And it take zirconium as matrix, significantly improves the preparation cost of material, and its elastic memory performance is not satisfactory.
To sum up, all there is such or such defect in the above-mentioned various frame of prior art report, along with the raising of people's living standard, people more and more require the ornamental of frame and better properties, and existing frame can not meet the demands.
Summary of the invention
For the deficiencies in the prior art, an object of the present invention is the preparation method providing a kind of frame elastic memory alloy material, not containing nickel element in this alloy material, and by the allotment of alloying element, material is made to have elastic memory performance, and Young's modulus is high, thus overcome above-mentioned defect of the prior art.
To achieve these goals, the present invention adopts following technical scheme:
A preparation method for Elastic memory alloy material for spectacle frame, the chemical composition of this alloy material can be made up of following component with (weight) percent basis: Zr 10-12%, Nb 6-8%, Al 11-13%, Cu4-6%, Mg 5-7%, Zn 2-4%, Ag 1-2%, Ce 0.5-1.5%, 0≤0.05%, N≤0.01%, H≤0.02%, surplus is Ti and inevitable impurity, and described preparation method comprises following preparation method:
1) smelting and pouring: by said ratio, the raw material such as ingot metal, master alloy is put into induction furnace and melt, liquation is evenly tested and adjusting component afterwards, it is made to meet above-mentioned scope, then tundish is imported, adjustment teeming temperature makes its superheating temperature be about 35-45 DEG C, and poured in copper water mold and carry out continuous casting, control casting speed is 0.3-0.5 m/min, obtain continuously cast bloom, continuously cast bloom is the square billet of 50 × 50mm;
2) hot rolling: continuously cast bloom is heated to about 980-1020 DEG C, is incubated about 15-25 minute, is then rolled, and finishing temperature is roughly 860 DEG C, obtains the wire rod of 10 × 10mm after rolling;
3) cold drawing: technique routinely, by cold drawn for the wire rod after the hot rolling shape and the specification that pull into frame;
4) thermal treatment: by the heating materials after cold drawing to about 260-280 DEG C, is incubated about 4-6 minute.
The various defects of conventional pure titanium and its alloys frame are referred in the introduction although above-mentioned, but due to the good biocompatibility of titanium alloy, in addition titanium alloy is also the important constituent element of shape memory alloy, therefore, the present invention is still using titanium as matrix element, but by redesigning its alloy element, thus overcome the defect of conventional titanium alloy frame in prior art.
Though the present invention have employed titanium elements, but no longer adopt Ni element conventional in memorial alloy, thus avoid the health problems such as the allergy brought by Ni, simultaneously by the content of the alloying elements such as allotment Zr, Nb, Al, Cu, Mg, and keep the elastic memory performance of TiNi alloy.
Add appropriate Ag element in the present invention, on the basis strengthening shape-memory properties, Ag significantly can strengthen the anti-microbial property of alloy, and this performance is for being important with the material that human body skin directly contacts.
The present invention also adds appropriate Zn element, to improve mechanical property, coordinates Zr, Nb, Al, Cu element, makes the Young's modulus of titanium alloy be greater than 75GPa.
The present invention adds appropriate Ce element, has and can change inclusion morphology, improve cold-forming property, improves the action effects such as elastic memory performance.
From above-mentioned, the present invention is by adjusting composition and the content of alloying element, overcome the defect of titanium alloy frame of the prior art, the content of above-mentioned each alloying element determines on the basis of great many of experiments, and reach coordination technique effect between each element, achieve the technique effect that 1+1 is greater than 2.The mechanical property of alloy material prepared by the present invention, elastic memory excellent performance, and not containing harmful Ni element, possess the anti-microbial effect of spectrum simultaneously, and therefore, excellent performance, simultaneously moderate cost.
