Synthesis and characterization of nanostructured materials based on Fe50Co50 and Fe75Co25

“…From Figure 7a, it could be observed that the crystallite size decreased from a value of 173.7 nm at 0 h down to a value of 13.6 nm at 30 h of milling for the Fe phase. These results differ from the values reported by Yepes et al (2014) who found a crystallite size of 7.5 nm at 35 h of milling. The difference between these values could result from the experimental conditions used for the mechanical alloying process of the powders.…”

“…The decrease in size of aggregates particles as the milling time increases is characteristic of the milling process. All the observations for Fe 50 Co 50 agree with those obtained for the same composition milled for 8, 20 and 35 h (Yepes et al, 2014).…”

“…SEM micrographs for the powders milled 15 h are shown in Figure 1c. Aggregates of powder particles can be seen, as a result of the flattening, welding, fracture and rewelding of powders, which is a typical feature of the mechanical alloying process for ductile-ductile systems, as reported in the literature (Zeng et al, 2007;Chermahini et al, 2009a;Chermahini et al, 2009b;Shokrollahi, 2009;Akkouche et al, 2011;Chitsazan et al, 2011;Yepes et al, 2014).…”

Thermal Characterization of Fe50Co50 and Fe65Co35 Nanostructured Alloys

“…It should be noted that the composition of the Fe50Co50 and Fe65Co35 nanostructured powders were formed after 8 hours of milling and the size of the crystallite reduction with the increase of the milling time. However, a lower value in the crystallite size was obtained after 7.5 nm to 35 hours of milling (Yepes et al, 2014). From the aforementioned investigations, it was possible to demonstrate that characterizations of the FeCo system have been made using scanning electron microscopy, x-ray diffraction, and vibrating sample magnetometry techniques.…”

“…This way, from the AM method, the structure and magnetic properties of the system are considered (Pérez et al,2012, Rincón et al, 2017. Similarly, the preparation of nanostructured powders of Fe50Co50 composition and their morphological characterization by SEM and DRX has been reported in (Yepes et al, 2014). It should be noted that the composition of the Fe50Co50 and Fe65Co35 nanostructured powders were formed after 8 hours of milling and the size of the crystallite reduction with the increase of the milling time.…”
