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.
