Abstract:

This study has been conducted to investigate the effect hydriding has on the electronic and magnetic properties of FeTi and Fe 0.8Mn 0.2Ti using the Mossbauer Effect. Experiments were conducted using the 14.4 kev Mossbauer radiation from Fe57 at temperatures between 4.2 K and 298 K. Studies were made of the changes in isomer shift and linewidth upon hydriding. Our results indicate that hydriding FeTi and Fe 0.8Mn 0.2 Ti causes phase changes in the crystals from an alpha phase to either a beta andor gamma phase. These studies also indicate that although there is a major change in the pressure composition isotherm upon alloying with manganese, there is no change in the electronic structure of the iron.
