Abstract

The paper illustrates the effect of 0.2–0.7 T magnetic fields on aluminum alloy creep. The creep of the alloy, following its preliminary holding in a constant magnetic field, was found to augment, demonstrating its magnetic memory. The dependence of creep on the induction magnitude of a constant magnetic field B was revealed, where the alloy creep proliferates linearly with an increase in B. The alloy was established to comprise Fe-Al (Fe4Al13) type microinclusions identified by electron microscopy, magnetometry, and diffractometry. Plausible mechanisms for modifying the states of ferromagnetic microinclusions and the aluminum matrix around them under the action of a magnetic field are discussed.
