Abstract: Electromagnetic emission accompanying the serrated deformation of the aluminum–magnesium alloy Al-6Mg has been revealed and studied experimentally. By means of high-speed video recording and a complex of methods for measuring the strain, load, and electric potential, it has been found that there is a relation between the electromagnetic emission signals and the dynamics of deformation bands. Possible mechanisms of the generation of electromagnetic signals have been discussed.

Keywords: Magnesium Alloy, Oxide Film, Deformation Band, Force Response, Electromagnetic Emission.
