The wide-temperature range memory alloy disclosed by the invention has extremely high memory properties, and the elastic deformation performance of the wide-temperature range memory alloy is extremely excellent.
Description
Technical field
The present invention relates to a kind of alloy material, particularly, relate to a kind of wide temperature memorial alloy and preparation method thereof.
Background technology
Memorial alloy is one of industrial indispensable visual plant, can the quality of its quality is determining safely, economical, produce constantly.The memorial alloy working conditions is harsh, and its working medium major part is the material inflammable, explosive, that perviousness is strong, and minimum operating temperature can reach 4K, and extreme service presure reaches 10MPa.The liquid nitrogen bottle that uses in utilizing the device of liquid nitrogen refrigerating at present has certain slit, even when environment on every side reaches needed low temperature, liquid nitrogen in the liquid nitrogen bottle also still continues to outflow, so in the working process of refrigeration, cause the very large waste of liquid nitrogen, and also reduced the working hour of refrigeration plant.Present memorial alloy can be applied in ultra-low temperature surroundings, such as the Working environment under the liquid nitrogen temperature.But but can not work in than under the wide temperature range.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defective, and a kind of wide temperature memorial alloy is provided, and it has the operating temperature range of non-constant width, under this temperature range, and memory performance, its elastic deformation performance is extremely excellent.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:

Particularly, finished by the component preparation of following weight part:
Zn:28 part, Ti:12 part, Al:55 part, Fe:14 part, Cu:18 part, Cr:5 part, CaO:1 part, Ni:8 part; MgO:1.2 part.
The preparation method of wide temperature memorial alloy may further comprise the steps
(1) 20 mesh sieves is crossed in described former abrasive lapping;
(2) with raw material in 1500 degrees centigrade of lower meltings;
(3) after the melting when the aluminium alloy temperature reaches 1400 ℃, the insulation leave standstill 30min, then in vacuum induction furnace, pour into ingot casting; Carry out anneal after the ingot casting cooling, anneal is to be heated to 600 ℃ of insulations furnace cooling after 20 hours;
(4) surface is removed in turning processing after the cooling, forges extruding, 600 ℃ of temperature;
(5) cold or hot drawing material requested.
Beneficial effect of the present invention:
Wide temperature memorial alloy of the present invention just has the deformation function at a lower temperature, can make multiple temperature control device, can make temperature control circuit, temp .-control valve, and the pipeline of temperature control connects.Utilize memorial alloy of the present invention can make automatic fire hydrant--the temperature of catching fire raises, and the memorial alloy distortion makes valve opening, the water spray fire fighting; But the connection of production machinery part, the connection of pipeline; Utilize electrically heated to change temperature, the distortion of interface memorial alloy, can make interface closely drip (oil) do not leak; Can make the antenna of bootstrapping of the area hundreds of square meter of space station--make on the ground large-area parabola shaped or plain aerial first, be folded into one, take space to airship, temperature transition is from generate original big area and shape.
