“…Considerable attention has been devoted to the Fe-based nanostructured alloys because of their unusual mechanical and magnetic properties which stem from the refinement of the crystallite size to the nanometer scale and from the enhanced density of defects [1][2][3][4]. Mechanical alloying is a non-equilibrium processing tool which can be used to produce metastable phases, amorphous and nanostructured alloys as well as metal/non-metal composite materials [5][6][7][8][9][10].…”

“…The value of saturation magnetization (M s ) was found to be approximately 80 emu/g, which is approximately same as that of nanocrystalline Ni 3 Fe. [47] The hysteresis curve for compacted sample is shown in Figure 19. It can be seen that the area of the hysteresis loop is very small.…”

A bulk nanocrystalline 80Ni-15Fe-5Co (wt pct) soft magnetic material was successfully produced via ''mechanical alloying-explosive compaction'' route. A rapid grain refining was observed during initial 12 hours of milling in high-energy planetary ball mill, followed by a level-off trend. A comparison of crystallite size of 125-hour-milled mechanically-alloyed (MAed) powder (10 nm) and explosively-compacted material (15 nm) showed negligible grain growth during explosive compaction. It has been shown that no phase change was brought about by the explosive compaction of the milled powder, and Ni 3 Fe remained the predominant phase in both MAed and explosively-compacted material. A possible mechanism of densification of flaky MAed powder during explosive compaction has been proposed, which consisted of the plastic deformation of powder particles into elongated shape followed by joining and folding of elongated particles. This process produced a continuous network of elongated and folded particles in the compact. The bulk nanocrystalline material showed improved magnetic properties, such as high Curie temperature and negligible core loss, making it a promising soft magnetic material for applications involving high temperatures and changing magnetic environment.

“…Fe -Ni alloys around Permalloy composition are well known for their performance as soft magnetic materials. The alloy from Fe-Ni system obtained by mechanical alloying process has been the subject of several researches during the years [10,11]. Among the alloys from Ni-Fe system, the synthesis of Ni 3 Fe intermetallic compound by mechanical alloying from elemental powders is one of interest [12,13].…”

Abstract:The mechanosynthesis of Ni 3 Fe intermetallic compound was carried out in a planetary mill. The effects of milling parameters such as balls diameters and ball milling speed defined by the vials rotation speed (ω) and the disk rotation speed (Ω), on morphology, microstructure and particle sizes of Ni 3 Fe powder were studied. It was found that the impact frequency represented by the number of balls from vials is an important parameter a milling process. The smaller grain sizes and particle was obtained when milling process was performed in high frequency rate of impacts together with high balls velocity, meaning high energy conditions.
