Shape memory alloys (SMAs) are “smart” materials that possess certain inherent properties, which make them suitable to be used in various automotive, aerospace, biomedical, and scientific applications. These alloys undergo extensive fabrication and processing operations while manufacturing actuators for automotive and industries; stents and surgical tools for medical field; engineered parts for aerospace, mechatronics, robotics, and many other fields. However, their fabrication and processing are not easy. This chapter introduces SMAs, highlights their properties and applications, and also discusses the difficulties encountered during their fabrication and processing along with the possible causes.
