Titanium aluminum boron shape memory alloy material, alloy, and production method and application of alloy

Abstract

The invention provides a titanium aluminum boron shape memory alloy material. The titanium aluminum boron shape memory alloy material is prepared from the raw materials in percentage by weight: 43-46%of Ti, 22-26% of Al, 28-35% of B, and the balance of a small amount of inevitable impurities. The invention further provides a production method of a titanium aluminum boron shape memory alloy. According to the production method, the titanium aluminum boron shape memory alloy material is sequentially subjected to smelting, rolling, heat processing, quenching, tempering, and finishing to obtain afinished product. The invention further provides the titanium aluminum boron shape memory alloy prepared by the production method, and provides application of the titanium aluminum boron shape memoryalloy in the fields of automotive industry, artificial intelligence, aerospace, transportation and other industries. The purposes of ensuring the shape memory alloy to have a shape memory transformation function, improving the mechanical strength to the maximum and achieving good toughness as well as lowering the cost of preparing the alloy as much as possible to prepare a shape memory alloy withyield strength greater than 600MPa and a economical cost are achieved.

Description

technical field [0001] The invention belongs to the technical field of memory alloys, and in particular relates to a titanium-aluminum-boron 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 transformation and its inversion. Shape memory alloy is currently the material with the best shape memory performance among shape memory materials. So far, people have found more than 50 alloys with shape memory effect. 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 up to send the artificial satellite to the predetermined orbit, it only needs...

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. Therefore, it is urgent to develop a shape with a yield strength greater than 600MPa. memory alloy
