Features of nickel-Titanium alloy shape memory alloy

1. Damping performance

Nitinol shape memory alloys have good damping due to the self-regulation of phase transition and the interface and motion generated during the phase transition.

2. Resistance

The resistance and strain of martensite nickel-titanium alloy shape memory alloy are linear during deformation. When a phase transition occurs, the slope of the curve decreases, but the linear relationship remains the same before and after the Martensite phase.

3. Shape memory

Nitinol shape memory alloy will automatically recover its shape after certain heat treatment. This change is the shape memory characteristic of Nitinol shape memory alloy. According to the recovery, shape memory can be divided into one-way shape memory, two-way shape memory and overall shape memory.

4. The super elasticity

The superelastic characteristics of Nitinol shape memory alloy are that it will deform under the action of external force and will return to its original state after the removal of external force. The superelastic deformation of Nitinol shape memory alloy will lead to martensitic transformation and no external force will lead to inverse martensitic transformation.
