“…It boasts higher deposition speeds, material efficiency, and lower costs compared to other DED processes [ 45 , 53 ]. Studies like Liu et al, 2022 [ 119 ] demonstrate the successful fabrication of homogeneous NiTi prints by optimizing source movement and wire feed speed. Additionally, interlayer temperature control plays a crucial role, with optimized temperatures around 200 °C leading to improved mechanical properties, microstructure, and reduced micropores [ 120 ].…”

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. Conventionally, Nitinol is predominantly produced in the form of wire or thin sheets that allow producing many required components. However, the manufacturing of complex shapes poses challenges due to the tenacity of the NiTi alloy, and different processing routes at elevated temperatures have to be applied. Overcoming this obstacle may be facilitated by additive manufacturing methods. This article provides an overview of the employment of additive manufacturing methods, allowing the preparation of the required shapes of Nitinol products while retaining their exceptional properties and potential applications.

“…16). One of the important SMAs is Ni-Ti alloys and considered as superior to other SMAs such as Cubased and Fe-based alloys owing to its higher strength, ductility and refined grain structure [338,339]. Ni-Ti alloys are biocompatible also, owing to which around 80% of products made up of these SMAs are medical related [340].…”

“…The accuracy of the model was verified by comparing the model predictions with the experimental data to further show that MTTs was affected by the interaction of laser power and scanning speed. [8] G. studied cold metal transfer (CMT) -fabricated NiTi alloys and it illustrated the fact that the micro-hardness, critical stress, and elongation of CMT-fabricated NiTi alloys increase monotonously from 256 to 290 HV, from 483 to 643 MPa and from 6.39% to 6.75%, respectively [9]. G. Crowther et al (2021) investigated a series of tensegrital wheels which showed that maintaining a class 1 tensegrity as much as possible improves force diffusion and general compliance and also that for high-tension tensegrity, positively constraining tendons at each node is critical to limit unintentional shifting of components, and to prevent parts from shaking loose from high-frequency vibrations [10].…”

Shape memory alloys (SMA) are innovatively designed for engineering applications including, but not limited to, medical devices, actuators, micromechanical systems, deployable structures, and elastocaloric devices. Prior to the manufacture of any component for the above mentioned applications, an extensive simulation study is recommended as the basic properties are required to be filled in the software. The unavailability of to-the-point literature makes this task difficult for researches. In this paper, an overview of binary NiTi based shape memory alloy is given, where its characteristic physical properties i.e. shape memory effect and super elastic effect, and mechanical properties like fatigue failure, stress-strain characteristics and yield and ultimate strength is stated for several different specimens prepared using thermomechanical methods.
