Shape memory alloys are primarily discussed in technical, scientific, and medical contexts in both Brazilian and American English. The term is standard in engineering departments, medical device manufacturing, and aerospace industries. In Brazil, as in the USA, these materials have become increasingly important in biomedical engineering, particularly in minimally invasive surgical procedures and dental treatments. The terminology is largely standardized across both countries due to international scientific communication.
