“…The Rietveld refinement reveals the formation of a partially amorphous structure of about ~78%, where nanocrystalline tetragonalFe2B, tetragonalFe3B and bccFeCo type phases were embedded for 3Nb powders [53]. Whereas, for 7Nb powders, the milling product is a mixture of amorphous (~73.6%), bccNb(B), tetragonalFe2B, orthorhombicFe3B and bcc FeCo type phases [54]. Further milling (up to 96 h) leads to the increase of the amorphous phase proportion for 7Nb and the mechanical recrystallization in the case of 3Nb mixture (Fig.…”

“…However, if the powder mixture contains both ductile and brittle particles (Fig. 2a), the hard particles may remain less deformed while the ductile ones tend to bind the hard particles together [10,36]. Cold welding is expected to be predominant in fcc metals (Fig.…”

“…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.
