Effects of Gd doping on Ni54Mn25Ga21 high-temperature shape memory alloy

The influence of Gd content on the properties of Ni54Mn25Ga21−xGdx alloy was investigated. Proper Gd doping significantly enhanced the mechanical properties. Complete recovery was observed in Ni54Mn25Ga20.9Gd0.1 alloy after heating when the pre-strain is less than 10%, while further doping decreased such properties due to the Gd-rich phase formation.
