Metals usually soften when they expand under heating, but a research team led by a City University of Hong Kong (CityU) scholar and other researchers have discovered a first-of-its-kind super-elastic alloy that can retain its stiffness even after being heated to 1,000K (about 727℃) or above, with nearly zero energy dissipation. The team believes that the alloy can be applied in manufacturing high-precision devices for space missions. The research team was led by Professor Yang Yong from CityU’s Department of Mechanical Engineering (MNE), together with his collaborators. The findings were published in the prestigious science journal Nature under the titled “A Highly Distorted Ultraelastic Chemically Complex Elinvar Alloy”.
