Abstract

The accommodation processes occurring at terminating twins, twin intersections and grain boundary-twin interactions are reviewed. It is shown that in the three situations, accommodation by slip and twinning can occur. Occasionally, microcracking is observed at a <110> twin intersection and a grain boundary-twin intersection. Argument is developed to reconcile these two sets of observations.
