Abstract
Shape memory alloys (SMAs), in comparison to other materials, have the exceptional ability to change their properties, structures, and functionality, depending on the thermal, magnetic, and/or stress fields applied. As is well-known, in recent decades, the development of SMAs has allowed innovative solutions as alternatives in biomedical applications, advanced engineering structures for aerospace and automotive industries, as well as in sensor and actuation systems, among other sectors. Irrespective of this, design and engineering with these special smart materials requires a solid background in materials science in order to consolidate their importance in these fields and to broaden their relevance in other new applications. The goal of this Special Issue is to foster the dissemination of some of the latest research devoted to these special materials from different perspectives.
