Titanium-aluminum-copper shape memory alloy material, alloy and production method and application of titanium-aluminum-copper shape memory alloy

Abstract

The invention provides a titanium-aluminum-copper shape memory alloy material. The titanium-aluminum-copper shape memory alloy material is prepared from the components in percentage by weight: 46-53%of Ti, 26-34% of Al, 13-28% of Cu and the balance of a small amount of inevitable impurities. The invention further provides a production method of a titanium-aluminum-copper shape memory alloy. The production method of the titanium-aluminum-copper shape memory alloy comprises the step that melting, rolling, heat treatment, quenching, tempering and finishing are sequentially carried out on the titanium-aluminum-copper shape memory alloy material to obtain a finished product. The invention further provides a titanium-aluminum-copper shape memory alloy prepared by the production method. The application of the titanium-aluminum-copper shape memory alloy in automobile industry, artificial intelligence, aerospace, transportation and other industries is further provided. The problem of how to maximally improve the mechanical strength of the shape memory alloy while ensuring that the shape memory alloy has the function of shape memory transformation, and meanwhile, the cost of the alloy is maximally reduced to prepare the shape memory alloy with yield strength greater than 500Mpa and more economical cost are solved.

Description

technical field [0001] The invention belongs to the technical field of memory alloys, and in particular relates to a titanium-aluminum-copper shape memory alloy material, an alloy, a production method and an application thereof. Background technique [0002] Shape memory alloy is a material composed of two or more metal elements that has a shape memory effect through thermoelasticity and martensitic phase transformation and its inversion. Shape memory alloy is currently the material with the best shape memory performance among shape memory materials. So far, more than 50 kinds of alloys with shape memory effect have been found. There are many successful examples in the application in the aerospace field, such as the antenna on the artificial satellite can be made of memory alloy. Before launching an artificial satellite, the parabolic antenna is folded up and put into the satellite body. After the rocket lifts off to send the artificial satellite to the predetermined orbit...

AI Technical Summary

Problems solved by technology

As the shape of the antenna becomes larger and larger, it is bound to put forward higher requirements on the mechanical properties of the shape memory alloy used in the antenna. At present, the existing memory alloy can no longer meet its use requirements, so it is urgent to develop a shape with a yield strength greater than 500MPa. memory alloy
