Refined approaches to the use of the coincidence site lattice

摘要

This article considers the validity of the coincidence site lattice classification in grain boundary engineering in light of the fact that the coincidence site lattice∑ designation does not directly specify the crystallography at the boundaryplane itself The coincidence site lattice approach is overviewed by reporting selected parts of a recent large-scale survey of experiments on polycrystals that invoke a coincidence site lattice analysis. Second, results from pure nickel are presented that show how a population of grain boundaries can evolve via a fine tuning mechanism recognized by decreasing deviations from exact coincidence site lattice matching.
