Abstract
The faceting of two tilt grain boundaries (GBs) in 99.999% wt. purity Al bicrystals has been studied. The first GB is a coincidence twin Σ3 <110> GB (Σ is the inverse density of coincidence sites) and the second GB has a misorientation close to the Σ3 <110> with a tilt deviation of about 3 degrees. Orientation of grains along the GB has been controlled with the electron back-scattering diffraction method. The bicrystalline samples were coated with a layer of Sn– Al mixture and annealed at 873 K. Contact angles at the junction of the grain boundary and two solid/liquid interfaces were measured by optical microscopy. The ratio of grain boundary energy and solid/liquid interface energy has been calculated. Wulff –Herring plots and GB phase diagrams were constructed. The formation of smooth edges with rounded rough GB portions was observed in the grain boundary deviating from Σ3 <110>.
