Mössbauer effect investigations of FeZn alloy and analysis using charge shift model

Mössbauer studies of metallurgically prepared FeZn alloy reveal that it undergoes an irreversible phase change on heating. The new phase starts precipitating at temperatures below 403 K and causes an apparent decrease in quadrupole splitting. The results are analysed in the framework of charge shift model and it is suggested that the vibrations of iron ion in zinc are likely to be much less anisotropic than those of zinc ions in pure zinc.
