Determination of the Misorientation Dependence of the Relative Grain-Boundary Energy of Commercial-Purity Nickel (Preprint)

Abstract

Columnar-grained samples of commercial-purity nickel were analyzed to establish the relative energy of <001> tilt boundaries as a function of misorientation. For this purpose, an electron-backscatter-diffraction (EBSD) technique was used to determine the grain-boundary geometry and misorientations across grain boundaries at triple-junction locations in two-dimensional sections perpendicular to the sample fiber texture. Analysis of the triple-junction dihedral angles and misorientations revealed that the relative boundary energy followed a classical Read-Shockley dependence.
