Mechanical properties of wrought Mg alloys are significantly influenced, besides of hexagonal closed crystallographic (hcp) lattice of Mg, by a grain size and strong initial texture. It is generally accepted that twinning is an important deformation mechanism in Mg alloys and is intimately related to an anisotropy or asymmetry of mechanical properties at room temperature. The activity of individual deformation mechanisms during plastic deformation can be monitored by the acoustic emission (AE) technique. The influence of texture, initial stress conditions of samples, homogeneity and stability of microstructure on deformation behavior of wrought Mg alloys was studied using AE parameters. A detailed insight into microstructural changes was provided by X-ray and electron back scattered diffraction (EBSD) techniques.
