Document Summary
Slip systems site]) for the (100), (110), and (111) planes for fcc. Furthermore, the planar densities of the (100) and (111) planes are calculated in homework problem. R2 (b) for the bcc crystal structure, the planar densities of the (100) and (110) planes were determined in. Below is a bcc unit cell, within which is shown a (111) plane. (a) The centers of the three corner atoms, denoted by a, b, and c lie on this plane. Furthermore, the (111) plane does not pass through the center of atom d, which is located at the unit cell center. The atomic packing of this plane is presented in the following figure; the corresponding atom positions from the figure (a) are also noted. (b) Inasmuch as this plane does not pass through the center of atom d, it is not included in the atom count.
