The sample demonstrated a high crystallinity level with diffraction angles of 28.86, 32.14 and 46.55 which correspond to the characteristic of face-centred
cubic of copper lines indexed at (210), (111), and (222) Fig.

XRD patterns show the diffraction peaks of silver nanoparticles at 26 values for 33[degrees], 36[degrees], 42[degrees], 62[degrees], and 73[degrees] which matched with 110, 111, 200, 220, and 311 lattice planes of face-centred
cubic structure, respectively [35, 40].
In RVE3, the nanowires are distributed in a face-centred rectangular array, as shown in Figure 1(c).
For [C.sup.eff.sub.44], the arrangement of the ZnO nanowires in square array and in face-centred square array produces similar values.
In case of [e.sup.eff.sub.13], the values for RVEs with square array match the predictions of RVEs with face-centred square array.
While the PTA-welded layer material exhibited only face-centred
cubic lattice (fcc), the cast Stellite 12 showed, beside fcc structures, also hexagonal-close-packed (hcp) [epsilon]-martensite fractions.
However, since the Co matrix undergoes an allotropic transformation from the low-temperature hexagonal closed-packed (hcp) structure to the high-temperature face-centred cubic (fcc) structure and showed a hysteresis, a two-phase matrix exists in Co-Re alloys at intermediate temperatures.
The new reflections match a phase with face-centred cubic symmetry (designated fcc-2) but with a smaller unit cell than the original fcc Co phase (designated fcc-1) already present in ST condition.
The XRD patterns displayed the characteristic peaks of (Ca/Zn)[Al.sub.2][O.sub.4] with the standard pattern of face-centred cubic (fcc).
It can be seen that the observed diffraction peaks of all samples are corresponding to the standard pattern of face-centred cubic (fcc) Zn[Al.sub.2][O.sub.4] with dominant peak (311) at 38.66[degrees].
The XRD data showed that diffraction peaks of all samples were corresponding to the standard pattern of face-centred cubic (fcc).
