How does body heat affect nitinol
WebJan 20, 2024 · Heat treated nitinol wires were characterized by optical microscope, Energy-dispersive X-ray Spectroscopy (EDS) and mechanical tests.Results show that Ni4Ti3 phase was formed as a result of heat ... WebA simple circuit can be constructed using a battery, switch and a small length of nitinol wire, see figure 7. When activating a Nitinol wire wire using DC current it is important not to overheat the wire by keeping the current on too long. Overheating the Nitinol wire will degrade its properties. DC current doesn't heat the wire evenly.
