WebFor a cubic crystal, the distance of the specified plane from the parallel plane which passes through the origin is: d (8) a H2 K2 L2 where H, K, L are the Miller indices and a = length of a side of the cube. The proof of this is a simple matter of solid geometry. The lower the Miller indices, the greater the separation between adjacent ... WebSlip in body-centered cubic (bcc) crystals occurs along the plane of shortest Burgers vector as well; however, unlike fcc, there are no truly close-packed planes in the bcc crystal structure. Thus, a slip system in bcc requires heat to activate. Some bcc materials (e.g. α-Fe) can contain up to 48 slip systems. There are six slip planes of type {110}, each with …
