Processing of shape memory alloys research, applications and opportunities: a review

Abstract

Shape Memory Alloys (SMAs) are metallic materials with unique thermomechanical characteristics that can regain their original shape after deformation. SMAs can be used in various industries such as consumer electronics, automobile parts, aircraft components, and biomedical devices. In this paper, we review the current state of the art of SMA fabrication and their application in the aerospace, healthcare, and aerospace industries. Specifically, we focus on the influence of manganese (Mn) addition on Cu-Al-Ni shape memory alloys' structure, mechanical characteristics, and corrosion behavior, focusing on the incorporation of small and medium-sized enterprises (SMEs) in the analysis of cu-aluminum alloys. This study explores the integration of SME and superelasticity, critical phenomena in SMA behavior, and can be utilized to develop and evaluate SMA-based devices and structures, as well as to understand the mechanism behind SMA actuation and develop improved materials. FEM simulations are crucial for optimizing designs and enhancing performance in sectors like aerospace and healthcare. FEM simulations can also be used to predict the stress and strain of SMA-based devices and structures. This can help to reduce cost, improve efficiency, and reduce the risk of failure. Additionally, FEM simulations can help to identify potential weaknesses in SMA-based designs and suggest modifications or improvements.
