Dependence of subgrain dimensions and disorientation on dislocation density in crystals grown by the bridgman, kyropoulos, czochralski or stepanov method

Abstract The semiempirical relations earlier obtained for estimation of the dimensions of nucleating subgrains and their disorientation, and the equation for evaluation of disorientation of more coarse subgrains (micro‐ and macrosubgrains) have been tested experimentally on various materials (Zn, Pb, Sb, Bi, Ge, KCl, KBr, NaCl, LiF). If has been shown that the above parameters can be calculated in terms of the dislocation density in a crystal with an error of a factor of 1–4.
