We report on the development of a simple and efficient method to predict the structural transition and the bulk-to-nano transformation of spherical FCC and BCC solid nanoparticles using the surface atomic packing fraction (). For both structures, 's are maxima at radii equal to the nearest neig...
Answer to: Sketch the atomic packing of the following: a. The (100) plane for the FCC crystal structure b. The (111) plane for the BCC crystal...
The total number of atoms in 1 m3 is then 4×2.14×1028=8.56×1028 since an fcc cell contains four atoms. Furthermore, the mass of a copper atom is 63.57 times the mass of a hydrogen atom (which is 1.63×10−24 g) so that the mass of 1 m3 of copper, i.e. the density, is...
Using a multi-component glass-forming alloy as proof of principle, we quantitatively characterize the short- and medium-range order of the 3D atomic arrangement. We observe that, although the 3D atomic packing of the short-range order is geometrically disordered, some short-range-order structures ...

Given that the total volume of Cu in the material is 16%, it may be inferred that the volume fraction of the Cu nanoprecipitates is on the order of 1% (from above, the Cu-rich rods and interdendritic regions account for 15%). Taking all of the above Cu-rich FCC phases into account...
