Problem: (a) Derive planar density expressions for FCC (111) in terms of the atomic radius R. (b) Compute linear density value for this plane for aluminum.

FREE Expert Solution

(a)

Planar density, PD = number of atoms centered on the plane/ area

For (111) plane:

The number of atoms = (1/6)(3) + (1/2)(3) = 2
