DETERMINATION OF LAMELLAE ORIENTATION DISTRIBUTION IN A DIRECTIONALLY SOLIDIFIED LAMELLAR Pb-Sn EUTECTIC

摘要

X-ray anisotropic absorption can provide the information about the space distribution of lamellae in a lamellar two-phase material. In the present work the lamellae orientation distribution is determined by spherical harmonic analysis of the anisotropic absorption effect in a directionally solidified lamellar Pb-Sn eutectic sample.
