Nickel titanium, also known as nitinol, is a metal alloy of nickel and titanium, where the two elements are present in roughly equal atomic percentages. It is a shape memory alloy, and different alloys are named according to the weight percentage of nickel; e.g., nitinol 55 and nitinol 60.
Nitinol alloy (Ni-Ti or nickel‑titanium) is used widely in biomedical, automotive, aerospace, and other industries due to its effective Shape Memory Effect (SME). A new additive manufacturing process has made it possible to produce the most recent time-dependent 4D-printed Nitinol alloy objects with Shape Memory Effect .
In the many practical applications of Shape Memory Alloys (SMAs), the most commonly used material is NiTi (nitinol). While its full atomic-level understanding is still lacking, NiTi's shape-memory effect is widely utilized, especially in micro-electromechanical systems.
The NiTi alloy, known as Nitinol, represents one of the most investigated smart alloys, exhibiting a shape memory effect and superelasticity. These, among many other remarkable attributes, enable its utilization in various applications, encompassing the automotive industry, aviation, space exploration, and, notably, medicine.
Ti-rich Nitinol (NiTi) is characterized by its functional properties to restore its original shape after deformation due to a temperature-induced reversible martensitic phase transition. In this study, dense Ti-rich Nitinol free of cracks is successfully produced by means of Electron Beam Powder Bed Fusion (PBF-EB).
Nitinol alloys are named according to the weight percentage of nickel in the alloy. For example, nitinol 55 contains 55% nickel, and nitinol 60 contains 60% nickel. These alloys exhibit two unique properties: the shape memory effect and superelasticity.

Nitinol shape memory alloys exhibit a unique property, allowing them to remember their original shape after deforming at certain temperatures. This remarkable characteristic enables the creation of self-expanding stents that can be inserted into blood vessels at low temperatures and then expand to their original shape once inside the body.
In order to further expand the use of nitinol, efforts have been made to enhance its mechanical and shape-memory properties. HPT (high-pressure torsion), ECAP (equal channel …
