Paper Title:
Martensitic Transformation and Mechanical Properties of Fe-Doped Ni54Mn21Ga25 Alloys
  Abstract

Ni54Mn21-xFexGa25(x=0,1,3,5,7,9)polycrystalline alloys were prepared by the technique of directional solidification and the effect of substituting Fe for Mn on the martensitic transformation and mechanical properties of the alloys was analyzed. It was found that the Curie temperature increased with increasing substitution while the martensitic transformation temperature decreased. The Fe-doped Ni54Mn21Ga25 alloys exhibit excellent magnetic properties at room temperature; the typical Ni54Mn20Fe1Ga25 alloy shows a large magnetic-induced-strain of -1040 ppm at a magnetic field of 4000 Oe.
