Abstract

The deformation behaviour of alloys that are ordered to form an L10 or L12 superstructure after heavy plastic deformation has been studied. Alloys with the LI0 superstructure, such as NiPt, FePd, CoPt and CuAu, possess an optimum combination of high strength and plasticity after thermomechanical treatment. However, such properties were not obtained in Pd3Fe, Pt3Co or Cu3Au which have the L12 superstructure. The structure of FePd was examined by transmission electron microscopy upon annealing after heavy drawing and a set of typical superstructural states was found. The conditions needed to impart high strength and plastic properties to some ordered alloys based on noble metals are discussed.
