Can tensile nitinol ingots be used for shape memory applications?
Stretched nickel titanium ingot can be used for shape memory applications.
Nitinol alloy has shape memory effect, which is based on its unique crystal structure and phase transition characteristics. For example, in the medical field, the stretched nickel titanium ingot can be used to manufacture a vascular stent, the stent is stretched and compressed at low temperature, which is convenient to put into the vascular intervention device, and after entering the human blood vessel, under the action of body temperature (higher than the phase change temperature), the stent will restore the original design shape, open the blood vessel, and restore the normal circulation of blood.
