Description
Summary:The program entitled Study of Grain Boundaries in Ionic Bonded Solids, conducted over a two-year period, has been directed toward: (a) A systematic investigation of the substructure and mechanical strength of twist, tilt, and mixed orientations in bicrystals of NaCl, MgO and other materials; and (b) A study of the mechanical breakdown in polycrystalline samples of the above materials to determine the role of grain boundary misorientation in crack initiation and propagation.
