Abstract: High-temperature shape memory (HTSMA) alloys that can operate at temperatures well above 100 °C are attractive for many applications in the automotive, aerospace or energy-conversion industries. In addition to elevated phase transformation temperatures, these materials must feature suitable transformation strains, oxidation resistance, and microstructural stability to name but a few. Some of the materials proposed demonstrate good functional properties, but are brittle, and thus difficult to process.
