Nitinol

Nickel Titanium (also known as Nitinol) belongs to materials known as shape memory alloys. As a result in temperature change there is a thermoelastic martensitic phase transformation in the NiTi that is responsible for its properties such as shape memory effect, superelasticity, and high damping capability. Change / modification in the composition of the two metals and also different heat treatment. In most cases a trial and error process is required to optimize these factors for a particular application.
One such application is vascular stents to reinforce blood vessels in the human body.

Do you know if they are used

Do you know if they are used in cardial stents?
