Low-hysteresis shape-memory ceramics

A team led by Prof. Chris Schuh — of MIT at the time and now John G. Searle Professor of Materials Science and Engineering, and dean of the Robert R. McCormick School of Engineering and Applied Science at Northwestern University — and MIT professor of the practice Greg Olson has through a combined technique including computational thermodynamics, phase transformation physics, crystallographic calculations, machine learning developed a new shape-memory ceramic material that sets the record for low hysteresis — approximately an order of magnitude better than common shape-memory ceramics and 5x better than the previous best such materials — putting them into the same range as those of more common metal shape-memory materials.
