“…In addition, the increasing complexity of these applications has resulted in the design of new nanomaterials and thus, the design/invention of new generation of nanoparticles. For this reason, an intensive research is still in development, particularly on the relationship between microstructure and magnetic response of these nanostructured alloys [2,3,4].…”

“…Accordingly to the results, all the prepared alloys were composed of two binary FeSi and Fe 3 Si phases and of two ternary Fe 3 Al 2 Si 3 and AlMoSi phases, and the lattice parameters are shown in Table 1. Compared to the work of others [34][35][36], the short-term MA formed only intermetallic phases instead of solid solutions, which are created during much longer process durations. It was discovered that the different amount of the Mo and Ni addition did not change the phase compositions within the tested range of chemical compositions.…”

Short-term mechanical alloying and compaction by spark plasma sintering was used for the production of FeAl20Si20Mo20-XNiX (X corresponds to 5–15 wt %) alloy, which showed an ultrafine-grained microstructure with dimensions of phases around 200 nm or smaller. It was found that the addition of Mo and Ni to the FeAl20Si20 alloy results in the formation of the AlMoSi phase compared to the three-phase FeAl20Si20 alloy, which initially contained FeSi, Fe3Si, and Fe3Al2Si3 phases. All the investigated alloys increased their hardness, reaching up to 1401 HV 1 for the FeAl20Si20Mo5Ni15 alloy, which contained in total 58.5% of the FeSi and Fe3Al2Si3 phases. As a result, all the prepared alloys showed one order magnitude lower wear rates ranging from 3.14 to 5.97·10−6 mm3·N−1·m−1 as well as significantly lower friction coefficients compared to two reference tool steels. The alloys achieved high compressive strengths (up to 2200 MPa); however, they also exhibited high brittleness even after long-term annealing, which reduced the strengths of all the alloys below approximately 1600 MPa. Furthermore, the alloys were showing ductile behavior when compressively tested at elevated temperature of 800 °C. The oxidation resistance of the alloys was superior due to the formation of a compact Al2O3 protective layer that did not delaminate.

“…And the chemical diffusion needed for solid reaction is enlarged by the powder with excess crystal defects and the transiently increasing temperature generated during ball-milling process. The diffusion among elements and the huge differences in diffusion in amorphous phase impose a kinetics constraint on the formation of the equilibrium phase, which is beneficial for forming amorphous base [21].…”

The microstructure and strain of gas atomization and water collection Fe73Si3B24 soft magnetic alloy powder treated by high energy ball milling were investigated via SEM and X-ray diffraction. And the magnetic properties of those powders were studied via VSM (Vibrating Sample Magnetometer). The results show that the atomization powders almost exhibited spheric or ellipsoidal shape. The averaged particle size was 104.94 μm. The main phases were composed of α-Fe (Si) and amorphous phase. As ball milling time went on, the interplanar space, amount of amorphous and crystal microstrain of the powders increased, while the grain size decreased. The peak for the (110) crystal plane of α-Fe (Si) phase widened, while the peaks for (200), (211) crystal planes weakened. These three peaks shifted towards to small angle direction. The saturation magnetic induction of treated powders was steady, and the coercivity of samples increased.
