M. Humbert et al., A non-linear positive method to reconstruct the parent textures from the inherited textures in phase transformation, J APPL CRYS, 33, 2000, pp. 206-212
The orientation distribution function (ODF) of the parent phase is reconstr
ucted from the inherited ODF of the transformed phase, provided that the la
ttice symmetry of the parent phase is higher than that of the inherited one
and that the orientation relation between both phases is known. In the cas
es of experimental errors or variant selections, the positivity of the ODF
of the parent phase is ensured by assuming that it is of quadratic form. (C
