Orienting grains with{110} surface traces

Abstract

Analytical equations for cubic crystals are developed relating a grain or crystal surface orientation to the angles between {110} traces on the surface.This allows easy and rapid orientation determinations with a computer with as high an accuracy as the trace data will permit. If the {110} intertrace angles can be ascertained with high precision, then four trace directions will usually suffice to give a unique grain or crystal surface orientation. Otherwise, more than four trace directions may be required. © 1986 The Metallurgical of Society of AIME.
