Bao'anShape memory alloy spring

The shape memory effect of nickel memory springs originates from the reversible phase transformation process of its internal microstructure with temperature changes. In the high-temperature austenite phase state, the spring has a specific initial shape. When the temperature decreases to the martensite phase transformation temperature range, the internal structure of the alloy transforms into the martensite phase, at which point the spring can undergo plastic deformation under external force. However, when the spring is heated again and the temperature rises above the austenite phase transformation temperature, the martensite phase will reverse to the austenite phase, and the spring will automatically recover to its pre-deformed state, as if it “remembers” its initial shape. For example, in some temperature control devices, the nickel memory spring is stretched and deformed at low temperatures. When the ambient temperature rises to the set value, the spring quickly recovers to its original state, thereby triggering corresponding mechanical actions or circuit switches.
