High Temperature Synthesis of Shape Memory Titanium-Nickel Superelastic Alloys: A Mini-Review

Abstract

Currently, the synthesis technology of porous Ti-Ni-based alloys with shape memory effect is being extensively studied and has attracted significant interest in various fields of application. Due to their unique functional properties, such materials are widely used in medicine, high-precision instrument manufacturing, as well as in aerospace and aviation technologies. However, many conventional production methods often require expensive raw materials and complex, energy-intensive equipment, which limits their industrial efficiency. To address these challenges, self-propagating high-temperature synthesis (SHS) is proposed as an alternative technology. The ability to achieve high temperatures through internally generated heat from exothermic reactions enhances the energy efficiency of this synthesis method while reducing the need for external heat sources. As a result, the obtained product exhibits structural uniformity, and the overall production costs are minimized. This scientific review comprehensively explores the potential of producing Nitinol via the SHS method, as well as the structural and functional properties of the resulting material, and the influence of synthesis parameters on material quality.
