Abstract
The energy and structure of the [100] twist and tilt grain boundaries in aluminium have been studied by fracture stress and dihedral angle measurements. The relative boundary energy was estimated as a function of misorientation. The fracture stress and the dihedral angle show a discontinuous change at a temperature, suggesting a drastic change in the grain boundary energy at this temperature. This transition temperature was measured as a function of misorientation.
