Description
Technical field
The present invention relates to technical field of alloy material, particularly a kind of frame preparation method of elastic memory alloy material.
Background technology
The traditional eyewear frame material adopts BZN15-20, this material is because having better technique and use properties large usage quantity in glasses are made, but because of its nickel content up to 13.5-16.5%, and so that the cost increase, in order to reduce cost, CN101967580A discloses a kind of Glasses structure material, and its content that has reduced nickel is to 7-9%.But because the Ni element can produce anaphylaxis and have carinogenicity part population, the above-mentioned patent application that therefore still contains nickel element can not overcome this problem.
In addition, existing this class frame material composition is simple, corrosion-resistant, general frame uses 3-6 after each month because the corrosion of framework metal material surface, cause its send out old, send out black, not only affect the attractive in appearance of glasses, also can impact HUMAN HEALTH; The rigidity of material used of frame is larger in addition, in case 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, conventional pure titanium and the frame of titanium alloy have been developed in the prior art, although titanium alloy has preferably solidity to corrosion, as disclosing a kind of titanium alloy frame material in the prior art, its chemical ingredients 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, has limited the application of titanium alloy aspect frame; And the Young's modulus of this titanium alloy frame frame is less than 75GPa, and rigidity is little, and easily distortion is worn rear lax easily.
In order to overcome the defects 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 the frame of this patent application preparation is higher, but still has nickel element in its composition, still has the above-mentioned problem of mentioning; And it has significantly improved the material preparation cost take zirconium as matrix, and its elastic memory performance is not satisfactory.
To sum up, all there is such or such defective in the above-mentioned various frames of prior art report, and along with the raising of people's living standard, people more and more require the ornamental and better properties of frame, and existing frame can not meet the demands.
Summary of the invention
For the deficiencies in the prior art, one of purpose of the present invention is to provide a kind of preparation method of frame elastic memory alloy material, do not contain nickel element in this alloy material, and the allotment by alloying element, so that material has the elastic memory performance, and Young's modulus is high, thereby overcomes defects of the prior art.
To achieve these goals, the present invention adopts following technical scheme:
A kind of frame preparation method of elastic memory alloy material, the chemical ingredients of this alloy material can be comprised of following component in (weight) percentage ratio: 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 are Ti and inevitable impurity, and described preparation method comprises the method for being prepared as follows:
1) smelting and pouring: by said ratio the raw materials such as ingot metal, master alloy are put into induction furnace and melt, liquation is rear test and adjusting component evenly, make it meet above-mentioned scope, then import tundish, it is about 35-45 ℃ that the adjustment teeming temperature makes its superheating temperature, it is poured into carry out continuous casting in the copper water mold, and the 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 ℃, is incubated about 15-25 minute, then be rolled, finishing temperature is roughly 860 ℃, the wire rod of rolling rear acquisition 10 * 10mm;
3) cold drawing: technique routinely, with cold drawn shape and the specification that pulls into frame of the wire rod after the hot rolling;
4) thermal treatment: the material after the cold drawing is heated to about 260-280 ℃, is incubated about 4-6 minute.
Although the above-mentioned various defectives of in background technology, having mentioned conventional pure titanium and titanium alloy frame, but because the good biocompatibility of titanium alloy, titanium alloy also is the important constituent element of shape memory alloy in addition, therefore, the present invention still with titanium as matrix element, but by its alloy element is redesigned, thereby overcome the defective of conventional titanium alloy frame in the prior art.
Though the present invention has adopted titanium elements, but no longer adopt Ni element commonly used in the memorial alloy, thereby avoid the health problems such as allergy brought by Ni, the content by alloying elements such as allotment Zr, Nb, Al, Cu, Mg simultaneously, and keep the elastic memory performance of TiNi alloy.
Add an amount of Ag element among the present invention, on the basis that strengthens shape-memory properties, Ag can significantly strengthen the anti-microbial property of alloy, and this performance is for being important with material that human body skin directly contacts.
The present invention has also added an amount of Zn element, to improve mechanical property, cooperates Zr, Nb, Al, Cu element, so that the Young's modulus of titanium alloy is greater than 75GPa.
The present invention adds an amount of Ce element, has to change inclusion morphology, improves cold-forming property, improves the action effects such as elastic memory performance.
By as seen above-mentioned, the present invention is by adjusting composition and the content of alloying element, overcome the defective of titanium alloy frame of the prior art, the content of above-mentioned each alloying element is to determine on the basis of great many of experiments, and reach the coordination technique effect between each element, obtained 1+1 greater than 2 technique effect.The mechanical property of the alloy material of the present invention's preparation, the elastic memory excellent performance, and do not contain harmful Ni element, possess simultaneously the anti-microbial effect of spectrum, therefore, and excellent performance, cost is moderate simultaneously.
