Memory Alloy: The Living Material Revolution

Memory alloy, known as the "living alloy" due to its ability to respond over a million times, is widely applied in mechanical, electronic, and medical fields. Its mechanical applications include fasteners, and pipe joints, while in electronics, it finds use in fire alarms, connectors, and integrated circuit soldering. In the medical field, memory alloy is utilized in artificial heart valves, and spinal correction rods, among others.

Moreover, it plays a significant role in devices such as communication satellites, and color televisions, and in various sectors like navigation, aviation, and aerospace.

Memory alloy not only contributes to pipeline joining and automation control but also substitutes for welding, facilitating repairs, and assembly. For instance, the hydraulic systems of US naval aircraft extensively employ such joints, with no reported oil leaks or damages over many years. Memory alloy also proves convenient in repairing damaged ships and underwater oilfield pipelines.

Especially suited for thermal machinery and constant temperature automatic control, memory alloy has been developed into automatic opening and closing arms at room temperature, adjusting ventilation windows based on temperature changes. Additionally, memory alloy offers new possibilities in utilizing industrial cooling water, residual heat from nuclear reactors, etc., albeit its efficiency remains relatively low and requires further improvement.

In summary, the wide application and innovative design schemes of memory alloy make it indispensable in various fields, promising new avenues for future technological advancements.
