Electrochemical Emission during Discontinuous Creep of Aluminum‒Magnesium Alloy

Electrochemical Emission during Discontinuous Creep of Aluminum‒Magnesium Alloy Abstract It is experimentally established that the discontinuous creep of aluminum‒magnesium alloy AlMg6, deformed in an aqueous medium, is accompanied by discrete electrochemical emission: jumps of the sample electrode potential, which arise simultaneously with stress drops during the development of macroscopic step on the creep curve. It has been found (with the aid of high-speed video recording) that the electrode potential jump occurs simultaneously with nucleation and initial fast stage of deformation band widening. A possible mechanism of the occurrence of electrode potential jumps in an aluminum alloy under discontinuous creep conditions is discussed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Crystallography Reports Springer Journals

Abstract

Abstract It is experimentally established that the discontinuous creep of aluminum‒magnesium alloy AlMg6, deformed in an aqueous medium, is accompanied by discrete electrochemical emission: jumps of the sample electrode potential, which arise simultaneously with stress drops during the development of macroscopic step on the creep curve. It has been found (with the aid of high-speed video recording) that the electrode potential jump occurs simultaneously with nucleation and initial fast stage of deformation band widening. A possible mechanism of the occurrence of electrode potential jumps in an aluminum alloy under discontinuous creep conditions is discussed.
