Abstract

Shape Memory Alloys (SMAs) are memory-enabled materials capable of remembering their original shape upon heating owing to the shape retention phenomenon. The shape memory effect originates from the reversible transformation between austenite and martensite phases. These alloys are biocompatible, meaning they cause no harmful reactions in the human body, and they are also lightweight, corrosion-resistant, and characterized by an excellent strength-to-weight ratio. SMAs have revolutionized applications in civil engineering, biomedical, industrial, aerospace, automotive, and robotics. This study critically examines the properties, history, recent advancements, material behavior, and frontier research areas, emphasizing their capability to address complex engineering problems and foster future technological advancements.

Keywords
