u掺杂对Ni45Mn36In14Co5合金马氏体相变和物理性能的影响

In this paper, the effect of 5 at.% Cu substitution for Ni on the martensitic transformation, magnetic properties, and mechanical properties of Ni45Mn36In14Co5 alloy were investigated. The results show that the martensitic transformation temperature shifted to lower temperature, and the magnetic field sensitivity is significantly enhanced. At the same time, the mechanical properties have also been significantly improved. This indicates that the alloy has a strong sensitivity to composition and the significant effect of Cu element on improving alloy properties, which provided a reference for the composition design and performance improvement of this type of alloy.
