Abstract
Lightweight shapeshifting alloys
Shape memory alloys (SMAs) spring back into shape after they are deformed, a useful property for a variety of applications. Transition metal alloys, which are robust but dense, dominate the SMA landscape. Ogawa
et al.
report a new type of lightweight SMA made from magnesium and scandium, which has comparable properties to known SMAs but at significantly lower density. Although this magnesium-scandium alloy is limited to low-temperature applications, development of a new lightweight class of SMAs could be on the horizon.
