Deformation twinning in superlattice structures

The role of twinning in deformation and fracture behavior of ordered intermetallic compounds has been investigated from a viewpoint based on the crystallography of twinning. The conjugate relationship between the order twinning and the active slip system at elevated temperatures is identified in all the ordered structures considered. Implications of this conjugate relationship on the strength and ductility of ordered alloys are discussed.
