Fe is Tungsten structured and crystallizes in the cubic Im-3m space group. The structure is three-dimensional. Fe is bonded in a distorted body-centered cubic geometry to eight equivalent Fe atoms. All Fe–Fe bond lengths are 2.47 Å.

A collection of 16 metals with the face-centered-cubic (fcc) crystal structure, including stainless steels, Fe–Ni alloys and pure Ni, have been subjected to the same nitrogen ion beam...

Bond charges form a "crystal" with a fcc lattice with 4 "atoms" per unit cell. Bond charges in covalent solid origin : (1/8,1/8,1/8). Sbond-charge(hkl) = Sfcc(hkl)[1+exp(i /2)(h+k)+exp(i /2)(k+l)+exp(i /2)(h+l)]. For h=k=l=2: Sbond-charge(222)=Sfcc(222)[1+3exp(i /2)4]=4Sfcc(222) non …

XRD analyses revealed the presence of FCC (Fe,C), BCC Fe, graphite/graphene and trace amount of Fe2O3 phases. Raman spectra confirmed the existence of MLG shells.

In situ time-resolved X-ray diffraction (XRD) data were collected of a body-centered cubic (bcc) kamacite section that transforms to the high-pressure hexagonal close-packed (hcp) phase with...

2023年8月15日 · Since two-phase region is developed between the Fe–Co-rich BCC and Cu-rich FCC phase in ternary Fe–Co–Cu isotherm, it gives rise to two distinct three-phase equilibrium triangles (FCC-1 + FCC-2 + BCC) along with two FCC miscibility gap regions; one FCC-2 phase that is richer in Fe and the other being richer in Co.

2017年3月23日 · By increasing Ni concentration in FexNi100−x alloy, the phase transition from bcc to fcc crystalline structure was clearly indicated by the XRD data as well as the measured hysteresis loops. FORC diagrams demonstrated that the prepared samples consist of single-domain magnetic particles with a uniform particle size.

2020年6月5日 · The X-ray diffraction (XRD) analysis was conducted on a MiniFlex 600 diffractometer (Rigaku) at 40 kV and 15 mA with a Cu radiation source at 1.541 Å. The scanning speed was 5°/min with a step size of 0.01°. The peak identification was achieved by the built-in search-match function in JADE software.

The stacking fault energies of the fee alloy series Fe-28 Ni to pure Ni were investigated using X-ray diffraction line profile analysis. A minimum stacking fault energy of about 70 mJ/m2 occurs at the approximate composition of Fe-40 pct Ni.

2007年9月14日 · The X-ray diffraction (XRD) study revealed stability of the face centred cubic (fcc) over the hexagonal close packed (hcp) phase in the whole investigated pressure–temperature range. The study presents first investigations of elasticity of fcc phase of iron–nickel Fe 0.78 Ni 0.22 alloy.
