Effect of Static Magnetic Fields on Creep of Aluminum Alloy

Abstract

The necessity and urgency of studying plastic deformation of metals is determined by both scientific significance of the problem and requirements of practice. So the objective of this work is investigation of aluminum alloy creep under action of static magnetic fields. This subject matter is of practical importance for engineering since the parts of engineering constructions are subject to various loads which may lead to their damage or even creep rupture. Based on the experiments performed by us, it is found that creeping increases under stable magnetic field; the main features appear at the first creep stage. Investigation of these processes will help to predict time dependence of creep strain and its rate as well as durability and plasticity at destruction.

“…В литературе можно встретить описание магнитопластичности алюминия и в меньших полях ∼ 1 T при наблюдении смещений индивидуальных дислокаций [8], деформации с постоянной скоростью [9] и ползучести [10]. Эта группа явлений находит более экзотическую интерпретацию на основе представлений о влиянии магнитного поля на спин-зависимые реакции между дефектами структуры [8,11].…”
