Equations 7.1a and 7.1b, expressions for Burgers vectors for FCC and BCC crystal structures, are of the formwhere a is the unit cell edge length. Also, since the magnitudes of these Burgers vectors may be determined from the following equation:determine values of |b| for aluminum and chromium. You may want to consult Table3.1.
