Radius of fcc
WebIn crystallography, atomic packing factor (APF), packing efficiency, or packing fraction is the fraction of volume in a crystal structure that is occupied by constituent particles. It is a dimensionless quantity and always less than unity. In atomic systems, by convention, the APF is determined by assuming that atoms are rigid spheres. The radius of the spheres is … WebMar 17, 2024 · The lattice parameter of FCC structure increased caused by the large radius of manganese atom in the HEAs solid solution, and the hardness of the HEAs was changed with the manganese addition [18]. Besides, when the atomic ratio of manganese increased to 3 at%, the HEAs will no longer be the single FCC solid solution phase, and the BCC …
