The Effect of Heat Treatment on The Magnetic properties of The (Fe-Ni) Alloys Prepared by powder Metallurgy Method


The aim of this work is studying the binary system (Fe1-xNix ) with two ratios (X = 35 , 80) by using Powder metallurgy method. Magnetic properties have been studied at different heat treatment temperatures throw Magnetic Hysteresis loop. Several properties have been found such as Magnetic Relative permeability (µr) , Magnetic Susceptibility (χm) ,Coercive force (Hc) and Remained force (Br) for all Samples. All the alloys were found a ferromagnetic behavior and Sensitive to the heat treatment. The results were explained due to the change on the degree of magnetic moment orders with the change of heat treatment degrees.
