Study of The Influence of Chromium on A Cobalt Iron Alloy

The present work comes within the framework of research of new materials, with improved properties, which could be an important key for innovative applications. For this purpose, two types of alloys, a binary (Fe, Co) and a ternary (Fe, Co, Cr), were first synthesized by mechanical grinding at high energy, varying the grinding time. In a second step, all the samples were subjected to various characterizations, a structural study (X-ray diffraction), a morphological study (scanning electron microscopy "SEM"), a magnetic characterization (the "VSM" vibrating sample magnetometer And finally, an electrical study (eddy currents). Numerous and valuable information was then deduced to know the variations in the average lens size, the internal micro deformation, the cell parameter, the saturation magnetization, the remnant field, the coercive field as well as the Z impedance, according to a only parameter, the grinding time.
