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