In the range of 300—1000 K, the temperature dependence of internal friction (IF) in the multifibrous Cu—Fe composite obtained using a packet hydroextrusion is investigated. The character of dependence of the IF level and peaks’ parameters (recrystallization, Snoek, Snoek—Koester) of composites on the diameter of Fe fibres and the bulk content of Cu is determined. The physical mechanisms of relaxation processes occurring at different (macro-, micro-, and nano-) structural levels are discussed.
Key words: Cu—Fe composite, internal friction, diameter of fibre, interphase boundary, recrystallization, interstitial impurity.
