“…It is observed for the mechanically alloyed Fe-20% Ni powders that, the higher the shock power (see Table 1), the lower the crystallite size (see [33,34]. Generally, when the crystallite size decreases, the lattice strain increases [7][8][9][10], whereas, using the G5 planetary ball milling for mechanically alloying Fe-Ni powders, Hays et al [12] have shown that using FMP, the crystallite size decreases gradually as a function of the milling time with a particle size varying between 1 and 5 m, whereas, in SMP, the crystallite size decrease sharply versus the milling time with a particle size varying between 20 and 100 m. Using Spex 800 and Frisch P7 for mechanical milling Graphite nanocrystalline, Salva-Disma et al [35] have shown that the friction (shear) type milling generates a mechanical strain weaker than the shock mode, therefore leading to samples that are much less damaged.

“…New technological methods of preparation and treatment open possibilities to prepare the materials with well-known chemical compositions but exhibiting novel physical properties. This concerns also the mechanical alloying process, which allows preparing nanocrystalline Fe-Ni alloys characterized by a grain size of a few nanometers [5,[7][8][9][10][11][12]. Mechanical alloying (MA) is a solid-state powder processing technique involving repeated welding, fracturing, and rewelding of powder particles in a high-energy ball mill.…”

“…Moreover M S and M f has been found [5] to be strongly dependent on the microstructure of austenite. Kaloshkin et al [6] reported that the grain refinement of Fe-Ni alloys by MA suppresses the austenite-martensite transformation on subsequent cooling to room temperature. These findings are qualitatively in agreement with the results given here.…”

“…Basing on various studies of Fe-Ni alloys with variation of Ni concentration (see, for instance [13][14][15]) and previous results on iron meteorites studies [16][17][18] the values of H eff were related to various Fe(Ni, Co) phases in Isheyevo CH/CB. The sextet 1 with H eff ∼346 kOe was related to martensite α 2 -Fe(Ni, Co), sextets 2 and 3 with H eff ∼334 kOe and H eff ∼333 kOe were related to kamacite α-Fe(Ni, Co) and the sextet 4 with H eff ∼312-314 kOe was related to disordered taenite γ-Fe(Ni, Co).…”
