Shape Memory Alloys (SMAs) are a unique class of metallic materials that possess the remarkable ability to recover their original shape after deformation, upon exposure to certain stimuli such as temperature or stress. This distinctive behavior is attributed to a reversible solid-state phase transformation known as the martensitic transformation. This course provides a general overview of this unique alloy, its principles of behavior, different types, engineering applications for this unique alloy, and more. This course is general in nature, and would apply as suitable continuing education for: mechanical, electrical, biomedical, materials, chemical, and other engineering professionals whose job description may require a generalized knowledge of shape memory alloys and their applications.
