Paper Title:
Studies of Plastically Deformed Ni-Mn-Ga Ferromagnetic Shape Memory Alloy
  Abstract

A polycrystalline ferromagnetic Ni2MnGa alloy with chemical composition of 49.13 at % Ni, 27.48 at % Mn and 23.39 at % Ga was hot rolled at 10000C causing deformation of 27%, 57% or 69%. The influence of the rolling process on the structure and texture of the parent phase were analyzed by EBSD and by X-ray powder diffraction methods. All samples revealed presence of the reversible martensitic transformation. During the solidification process columnar grains were formed with the <110>B2 texture. Sample deformation done by hot-rolling caused texture evolution from the <110> via <100> to the complete random distribution.
