研究了Gd含量对Ni54Mn25Ga21− xGdx合金性能的影响。适当的Gd掺杂显著提高了材料的力学性能。当预应变小于10%时，Ni54Mn25Ga20.9Gd0.1合金在加热后可完全回复，而进一步掺杂会导致富Gd相的形成，从而降低合金的回复性能。
The influence of Gd content on the properties of Ni54Mn25Ga21−xGdxalloy was investigated. Proper Gd doping significantly enhanced the mechanical properties. Complete recovery was observed in Ni54Mn25Ga20.9Gd0.1alloy after heating when the pre-strain is less than 10%, while further doping decreased such properties due to the Gd-rich phase formation.
