THE DETERMINATION OF BIAXIAL ORIENTATION BY X-RAY DIFFRACTOMETRY
Abstract
The state of biaxial orientation of crystallites of a polycrystalline polymer may be determined by measuring the x-ray diffracted intensity from particular crystal planes (at a fixed Bragg angle) as a function of the azimuthal diffracted angle and of the sample tilt angle. The orientation distribution may be expressed in terms of two dimensional pole-figure projections or in terms of biaxial orientation functions. Geometric relations governing the determination of such pole figures are stated, and a computer program is presented for their calculation. Correction factors for absorption, polarization and incoherent scattering are included in the program.
