The development trend of shape memory alloy

Nitinol alloy shape memory material is a special material that combines perception and drive, while nitinol alloy shape memory alloy is a very critical part of nitinol alloy shape memory material. Nitinol alloy shape memory alloy refers to a class of alloys whose shape is deformed into another shape at a certain initial state at low temperature, and then heated to increase its temperature and re-deform it into its original shape. The original shape of the alloy.

(1) Iron-based shape memory alloy

Iron-based shape memory alloys have the advantages of strong processability and high cost performance, and have attracted much attention from many fields of society. The recent research work is mainly on the phase transition mechanism and its influencing factors. Select suitable shape memory alloys for distribution and exploration, improve the level of preparation technology, and improve the performance of the alloys at the same time.

(2) Magnetic shape memory alloy

This shape memory alloy will produce strain under the huge action of the magnetic field, and the operating frequency of the shape memory alloy will be raised from the temperature-controlled state to the magnetron state, giving full play to the function of magnetically driving the shape memory alloy. Sensors and drive components made of magnetic shape memory alloys play an important role in the petroleum industry, the electronics industry, and the aerospace industry.

(3) High temperature shape memory alloy

Many ordinary alloys can only be used at 100 degrees Celsius, while more and more shape memory alloys can be used at environments exceeding 100 degrees Celsius. For example, the shape memory alloy components in a nuclear reactor have an operating temperature of more than 600 degrees Celsius. Therefore, it has become an important trend to study and manufacture high-temperature shape memory alloys, and the use of high-temperature shape memory alloys in many fields has good prospects.
