Nickel-titanium alloy can be deformed arbitrarily when it is below the phase transition tem- perature, and the alloy can recover its initial shape when the environment or its own tempera- ture exceeds its phase transition temperature. Utilizing the deformation function of the
memory alloy at a specific temperature, a variety of temperature control parts can be made, which can be used to make temperature control circuits, temperature control valves, and piping connections for temperature control.
Nickel-titanium shape memory alloys are deformed in the state of mother phase (above thephase transition temperature), stress-induced martensitic phase transition occurs, and aferunloading, the inverse phase transiion of stress-induced martensitic phase transition occursand the macroscopic manifestation of the shape is automatically recovered, and the phenom-enon that the strain in the process far exceeding the elasticity limit is completely or partiallyrecovered is called memory alloy superelasticity. The use of superelasticity can produce avariety of high life elastic devices, such as underwear memory steel ring, bone conductionheadset bracket, sports headset bracket, jewelry bracket and so on.
Nitinol memory alloys can form a stable passivation film with living organisms, and usingmemory materials that are close to the human body's temperature phase change temperaturecan be used to make cardiac stents, vascular stents, medical quide wires, dental arch wires.and bone grafting plates.
The relationship between resistance and strain is linear for martensitic Ni-Ti shape memoryalloys during deformation. The slope of the curve decreases when a phase transition occursbut the relationship remains linear before and after the martensitic phase.
