AbstractThis study presents an integrated approach using experimental high resolution electron microscopy, computer simulations and theoretical analysis, to provide a thorough atomic level investigation of grain boundaries. Examined here, are specific cases of pure aluminum grain boundaries. Energy calculations for the Sigma3 perfect twin, in a range of linear translational states, show that both the shape and location of the interfacial surface are important considerations.
