Abstract

The structure of compacted Cu60Fe40 powder in various stages of thermomechanical processing (with a logarithmic strain varied within e = 0−7.4) has been studied by X-ray diffraction. It is established that the atomic order evolution in this system is characterized by a certain critical strain (e = 4.6), at which a specific deformation-induced nanostructure is formed. In this structure, clusters of a bcc α-Fe phase with dimensions on the order of 200 Å are coherently conjugated with a polycrystalline fcc structure of copper, thus representing a new class of materials.
