REPRODUCIBLE TEXTURES.

Abstract

THE ORIENTATION DISTRIBUTION FUNCTION OF A TEXTURED POLYCRYSTALLINE MATERIAL MAY BE SPLIT INTO AN EVEN AND ODD PART; THE LATTER IS NOT REPRODUCIBLE FROM POLE FIGURE MEASUREMENTS. THE CLASS OF TEXTURES CONTAINING ONLY A REPRODUCIBLE PART ISCONSIDERED. IN THE CASE OF AXIALLY SYMMETRIC TEXTURES (FIBER TEXTURES), THESE TAKE ON A SIMPLE FORM ALTHOUGH THEY ARE NOT THE ONLY TYPE OF REPRODUCIBLE TEXTURES. A SAMPLE HAVING AREPRODUCIBLE TEXTURE IS CENTROSYMMETRIC. REPRODUCIBLE TEXTURES CORRESPOND TO A NON-CONVENTIONAL CENTER OF INVERSION AS AN ELEMENT OF SAMPLE SYMMETRY AND VICE VERSA.
