M. Humbert et N. Gey, Restitution conditions of the parent cubic texture from the inherited hexagonal texture in the beta-alpha phase transformation, J APPL CRYS, 32, 1999, pp. 21-26
Different factors calculated from the C coefficients of the inherited orien
tation distribution function (ODF) allow us to check the importance of the
variant selection. When no variant selection or a slight variant selection
occurs by the cubic-to-hexagonal phase transformation, it is possible to ca
lculate the ODF of the cubic parent phase present at high temperature from
the ODF of the inherited hexagonal phase at room temperature. When a strong
er variant selection occurs, qualitative information about the parent ODF c
an be obtained by using a specific correlation function, which we have name
d R(g).
