摘要
In this survey, the results of the available studies are generalized and the effects of thermomechanical treatment on the structure and the magnetic, mechanical, and electrical properties of Cu-Fe composites produced by the methods of casting, powder metallurgy, and severe plastic deformation are analyzed. The primary attention is paid to the method of packet hydroextrusion, which makes it possible to achieve a wide spectrum of diameters (3 nm−2 mm) of iron fibers and of the amount of fibers (1–8 × 108) in these composites with varying volume content (10–60%). The physical mechanisms of the revealed effects of the structural modification of the physicomechanical characteristics on different scale (macro, micro, and nano) levels are discussed.
