The effect of Al on the crystal structures of the high-entropy alloy AlxCrFeCoNi is discussed using first-principles electronic structure calculations. When the atomic configuration is totally random, AlxCrFeCoNi has the fcc structure. However, the total energy difference between the fcc and bcc ...
Calculate the radius of iridium at, given that Ir has an FCC crystal structure, a density of 22.4 g/cm^3, and an atomic weight of 192.2 g/mol. Calculate the Planar Density (atoms/nm^2) of Atoms in the (111) plane of BCC Molybdenum. The lattice parameter...

of bcc structure has more occupied states far belowEFand less occupied states close toEFcompared to that of fcc/hcp structure when thed-band is about half-filled29. This leads to a lower electronic band energy, which makes bcc structure more stable compared to the close-packed structure29. ...
so far research has focused on hard-sphere colloidal systems, which only exhibit an face-centred cubic (fcc) structure. This is in contrast with many metals which have body-centred cubic (bcc) crystal symmetry, especially at conditions used for processing, temperatures at or slightly below their...
Total-energy calculations for fcc and bcc silver had shown that if silver is forced to grow with a volume per atom > 10% larger than that of the well-known fcc silver, the total energy of the bcc structure gets below that of fcc silver. In this paper we present detailed electronic-stru...
The aim of this work is to shed light onto the way temperature may contribute to the attenuation of the dynamic yield point in FCC aluminium and BCC iron. Both materials are chosen because of their characteristic and opposite plastic behaviour under shock loading at different temperatures. Given ...
High resolution Cu Lx-ray absorption spectra of bulk fcc Cu metal are compared with those of thin Cu layers in Cu/Fe multilayers. Comparison of the measured fine structure with that obtained from a fully relativistic first-principles calculation for fcc and bcc Cu reveals that Cu is bcc in ...
