In an oxidized Titanium I have precipitatated Ti FCC lamelles in a HCP matrix. confirmed by XRD

In diff 1 I have indexed the HCP zone axis to the family of zoneaxises represented in the attached stereogram. I can index the FCC as . This is the relationship reported by many others in litterature. However if I tilt to another axis of the same HCP family in the stereogram (diif2), I get something I can't index. In both cases I can indentify the extra spots to the lamella, see darkfield. Can anybody come up with an explanation
