Morphological and magnetic properties in Fe-28.2Ni-0.5Ti, Fe-26.8Ni-1.5Ti and Fe-27.6Ni-4.2Ti alloys were investigated. Scanning electron microscopy (SEM), Mössbauer spectrometer, DSC and Vickers hardness measurements were used to determine the physical properties of the alloys. Mössbauer parameters including hyperfine field (Bhf), quadrupole shift (QS), isomer shift (IS), line width (W) and percentage relative area (RA) were determined. Morphological changes, Ms and As temperatures and hardness values were also evaluated depending on Ti content.
