Nitinol is an alloy of two metals, nickel and titanium. The two elements are present in roughly equal percentages. Different alloys are therefore named according to how much nickel they contain. Nitinol is widely used in automotive applications. Because of its shape memory and superelasticity, Nitinol is ideal for applications that require strength or pliability.

Molecular structure

Nitinol is a versatile metal alloy used in the treatment of arterial diseases. It can also be used to make blood clot filters or stents. It is ideal for use in vascular therapy because it changes its shape with phase transformation. Here, we will explore how Nitinol is shaped and its medical applications.

Nitinol, a combination of nickel and titanium, is also known as Nitinol. It is composed of about fifty percent nickel. It is also used in electronic equipment as a temperature sensor, variable resistor, and switch. It is also used in cell phone technology, including microphone booms and retractable antennas. It is also used in the manufacture of certain surgical implants.

Nitinol's crystal structure consists of one sphere each representing titanium and nickel. Figure 2 (a) shows the equiatomic structure. The Ms-value is the austenitic phase, while Mf-value is the martensitic.

Many biomedical applications have used Nitinol, such as bone fixation and orthodontic archwire. It is also used to make stents. Because of its low density and strength, it is suitable for this type surgery. It does have some drawbacks. Its oxidation properties are poor, and it can release nickel ions into the human body.

Nitinol can also be made to conform to a specific shape. This makes it a popular choice in medical devices. It is biocompatible and is therefore used in surgical instruments.

Nitinol's unique ability to adapt to different strains is another remarkable property. This makes it compatible with the human organism. Higher temperatures will see Nitinol form a cubic crystal structure. At lower temperatures it will change to a martensitic shape. This transition temperature is known as the transformation temperature, and it occurs at Ms and Mf temperatures.
