The Effect of Phosphorous on Microstructure and Magnetic Properties of Fe Based Alloys

In the present work، the magnetic properties of Fe-P alloys were investigated. The investigations showed that the magnitude of coercivity decreased by conducting two annealing treatments on samples. Samples having the highest amount of Phosphorous exhibited the lowest resistivity. Microstructural studies revealed that the prepared samples were free from Fe3P precipitate and the average grain size increased with an increase in the Phosphorous content giving rise to the decrease of hysteresis losses. Furthermore، amongst the whole prepared samples، Fe-1. 1at. %P alloy showed the lowest hysteresis loss and eddy current loss as well as the highest magnetic induction.
