Representation of Boundary Plane FZs.
Stereographic projections of FZs for the (a) Σ41a ([100] 12.68°) and (b) Σ5 ([100] 36.87°) CSL misorientations. To capture the inherent symmetry of the misorientations, the FZs are rotated from the [001] axis by half the disorientation angle, but cover a 45° swath of the sphere. (c,d) Standardized representation for the two FZs in (a,b) is accomplished by rotating the FZs down so that FZs of the same disorientation axis will appear identical.
