Role of local structural distortions in the variation of martensitic transformation temperature with e / a ratio in Ni 2 Mn 1+ x Z 1- x (Z = In, Sn or Sb) alloys
Ni Mn Z (Z = In, Sn or Sb) undergo martensitic transformation with transformation temperature ( ) scaling with the average valence electron per atom ( / ) ratio. However, the rate of increase of depends on the type of Z atom, with the slope of / curve increasing from Z = In to Z = Sb. Local structur...

(Z = In, Sn or Sb) undergo martensitic transformation with transformation temperature (
) scaling with the average valence electron per atom (
/
) ratio. However, the rate of increase of
depends on the type of Z atom, with the slope of
/
curve increasing from Z = In to Z = Sb. Local structural distortions are believed to be the leading cause of martensitic transformation in these alloys. A careful study of the Ni and Mn local structures in several Ni
Mn
Z
alloys with varying
/
ratio and the same Z atom, with the same
/
ratio but different Z atoms and with the same
but with different Z atoms and different
/
ratio, revealed that the difference between Ni-Mn and Ni-Z nearest neighbor distances decreases as the Z atom changes from In to Sb. This decrease in the local structural distortion accommodates a higher content of Mn until the
2
structure becomes unstable and the alloy undergoes a martensitic transformation. |
