Other major themes are ductility of thin films and nano-layers, ductility of metallic glass and composites, and recovery and grain growth. Some specific topics covered include the effect of grain size on defect density and internal stresses in sub-microcrystals, ultrahigh strength and ductility of Cu-Nb nanolayered composites, nanostructured Ti2448 biomedical titanium alloy, and the effect of aging on strength and ductility of ultrafine grained Al 6061 alloy.

This orientation of the twinned boundaries indicates that the twin-oriented domains form as a result of the formation of errors in the sequence of laying the atomic layers {111} of the FCC lattice of copper during grain growth. These errors at the solidification front may form as a result of the small difference of the free energies of the nucleation islands with the regular and irregular packing of the atoms in relation to the crystal surface (7).
