Microstructural investigation of a rapidly solidified FeSiC alloy

Structure, phase composition and magnetic properties of mechanically alloyed and annealed quasibinary Fe(70)Si(x)C(30−x) alloys

“…Because of the similarity of the X-ray diffraction patterns, Mössbauer spectra and temperature dependences of magnetic susceptibility χ(T) for all the compositions studied, they were presented only for Fe(70)Si(14)C(16) (see Figs. [3][4][5].…”

“…The variety of metastable Fe-Si-C phases with different compositions and crystal structures [1][2][3][4][5][6][7][8][9][10][11][12][13][14], such as amorphous [2,13], bcc and cubic [3], orthorhombic [4][5][6], triclinic [7,8], and hexagonal [1,9,12] ones, which have been referred to in the literature, is just striking. Furthermore, the information on chemical composition of the compounds formed within this system, namely, Fe 3 SiC, Fe 4 SiC, Fe 10 Si 2 C 2 [10], Fe 10 Si 2 C 3 [1], Fe 8 Si 2 C [7,14], Fe 9 SiC 2 [9], is far from being unambiguous.…”

Nanoscale metastable state exhibiting pseudotenfold diffraction pattern in Fe-based bulk metallic glass

“…In lower metalloid ͑B, C, or P͒ composition range ͑less than 20 at %͒, aside from the prism-type structures, crystal structures comprising coordination polyhedra with large coordination numbers ͑CN͒ have been reported in crystallization of various Fe-based metallic glasses. For example, as a crystalline phase, the ␣-Mn-type structure with CN12, CN13, and CN16 polyhedra was reported in Fe-͑Cr, Mo, W͒-C, 13 Fe-Si-C, 14 Fe-Si-P, 15 Fe-Nb-B, 16 and Fe-Si-Nb-B ͑Ref. 17͒ metallic glasses, and the -phase structure with CN12, CN14, and CN15 polyhedra was reported in Fe-Si-B and Fe-Cr-V-B metallic glasses.…”
