parents
(method of orientation)
variants of an orientation relationship
Syntax
ori_parents = ori_child * inv(mori.parents)
Input
mori |
child to parent orientation relationship |
ori_child |
child orientation |
Output
ori_parents |
all possible parent orientation |
Example
% parent symmetry cs_fcc = crystalSymmetry('m-3m', [3.6599 3.6599 3.6599], 'mineral', 'Iron fcc');
% child symmetry cs_bcc = crystalSymmetry('m-3m', [2.866 2.866 2.866], 'mineral', 'Iron bcc')
cs_bcc = crystalSymmetry mineral : Iron bcc symmetry: m-3m a, b, c : 2.9, 2.9, 2.9
% define a bcc child orientation
ori_bcc = orientation.goss(cs_bcc)
ori_bcc = orientation size: 1 x 1 crystal symmetry : Iron bcc (m-3m) specimen symmetry: 1 Bunge Euler angles in degree phi1 Phi phi2 Inv. 0 45 0 0
% define Nishiyama Wassermann fcc to bcc orientation relation ship
NW = orientation.NishiyamaWassermann (cs_fcc,cs_bcc)

% compute a fcc parent orientation related to the bcc child orientation
