“…Similarly, binary systems such as Fe-P and Fe-Co based alloys were also prepared by mechanical alloying and exhibited interesting properties [14,15]. In one hand, Fe-Co alloys attracted great attention due to their excellent soft magnetic and mechanical properties, which are found to be strongly dependent on the adopted fabrication method and subsequent heating treatment [16,17].…”

“…In the other hand, the transition metal phosphides alloys and their solid solutions demonstrated interesting magnetic properties which are greatly influenced by both the type of the crystal structure and the chemical composition; for instance it was reported that the lattice parameters and Curie temperature of Fe2-xP system changes significantly with the presence of small amount of impurities and the deviation of stoichiometry [20]. The role of the compound on the structure stability, phase composition and properties was mostly studied on binary Fe-P alloys that dependent on P concentration with a ferromagnetic ground state [14,21]. In recent years, great attention has been given to the thermal stability of transition metal phosphides nanomaterials [22,23].…”

This research work aims to investigate the mechanically alloyed Fe15Co2P3. Parametric Rietveld refinement method, of the obtained X-ray patterns, was performed for qualitative and quantitative phase analysis, structural, microstructural and mechanical properties. The ball-milled powder mixture crystallized within the face-centred cubic α-Fe(P) solid solution in equilibrium with Co75Fe25 phase. The crystallite size decreases reaching 100 and 200 nm respectively after 3h of milling. The highest values of the dislocation density, microstain and stored energy are registered for the α-Fe(P) solid solution. The studied mechanical properties manifest the brittle nature of the α-Fe(P) solid solution compared to the Co75Fe25 phase. The squareness ratio Mr/Ms and the coercivity values of the milled powders increase with increasing milling time and reach steady state after 2 h. The hysteresis loss energy and maximum permeability reach minimal values of 45*10− 4 W/m3 and 49*10− 3 H/m respectively, after 1 h of milling at the opposite of the switching field distribution.

“…MA is a solid state synthesis method to prepare nanocrystalline alloy/compound powders by milling the elemental powders in an appropriate ball mill. Extreme local pressures and temperatures, engendered for a small milling time during repeated ball-powder-ball collisions, lead to the powdered materials transfer by diffusion and eventually, to the formation of new phases which cannot be obtained by other techniques of preparation [4][5][6]. In this study, the chosen composition is Cu 70 Co 30 , which is quite different from all previous alloys in this system.…”

The Cu70Co30 alloy was developed by a non-equilibrium method of "mechanical alloying", from a mixture of copper powder and pure cobalt. The nanostructured alloy Cu-Co with grains with a size of about 12 nm, has different electromagnetic properties which are often superior to those of conventional solid alloy, because of the critical size effect. In this work we are interested in the electromagnetic properties of the synthesized material. Resistivity, eddy current and the magnetization evolution were studied. The frequencies selected for plotting the diagram vary from 100 Hz to 100 kHz. To satisfy the Weiss condition, the excitation field must be of the same order of magnitude as the field that characterizes the area of Weiss. For all prepared series, the evolution of the magnetization as a function of milling time was analyzed. The influence of milling time on the resistivity variation is shown.

The mechanical alloying process has been used to prepare nanocrystalline Cu70Fe18Co12 alloy from elemental Cu, Fe and Co powders in a planetary ball mill under argon atmosphere. The interdiffusion of Cu, Fe and Co leads to a heterogeneous solid solution with Cu-Fe-Co rich environments after 12 h of milling. The end product is a mixture of a highly disordered structure, fcc-Cu (Fe-Co), phase having different microstructural and structural parameters. For all the elaborate series, the evolution of coercive field and the remanence according to the time of milling is analyzed. The coercivity, Hc, decreases rapidly up to 8 h of milling to about 0.3 A/m and then the coercivity, increases to a maximum at 54 h. The influence of the time of milling at the resistivity of these alloys is shown.
