Close-packed planes

WebNov 18, 2013 · In fcc metals, slip generally occurs on {111} planes in 〈110〉 directions. The perfect Burgers vector is a/2〈110〉, which is a close packed direction, and represents the shortest repeat length in the crystal. The slip planes, {111}, have the largest interplanar spacing of those containing close packed directions.

Webname "close packed" refers to the packing efficiency of 74.05%. No other packing can exceed this efficiency (although there are others with the same packing efficiency). If we stack the cells into a lattice we notice that the … WebAug 28, 2024 · For silicon, the {111} planes are closer packed than the {100} planes. As a result, growth of a silicon crystal is therefore slowest in the <111> direction, since it requires laying down a close packed atomic layer upon another layer in its closest packed form. As a consequence <111> Si is the easiest to grow, and therefore the least expensive. huawei y5 lite dual sim settings https://redhousechocs.com
