What is the difference between shape memory alloy and common alloy?
Shape memory alloy is composed of two rare elements, which have shape memory function according to thermal ductility, austenite change and inverter power supply. Shape memory alloy is the best shape memory material at present. So far, 50 different types of aluminum alloys have been found to have shape memory effect. There are many successful applications in aerospace industry. Giant wireless antennas on satellites can be made of memory alloys. Before sending the satellite, the parabolic antenna is inserted into the main body of the communication satellite, and then the rocket is launched to send the satellite into the planned orbit, and then it is preheated. Because of its memory function, the telescope antenna can certainly repair the antenna and parabolic shape.
