Abstract
In this study, acoustic emission (AE) measurements were performed during tensile testing of sheets of four magnesium alloys in different orientations with respect to the tensile axis in order to investigate the influence of microstructure and texture on the deformation behaviour. AE measurements could especially be used for analysing the activity of twinning. It was shown that the grain size has an important impact on the AE count rates which was directly related to the activity of deformation mechanisms. Small changes in the texture can significantly affect the activity of twins. It was further shown that a weak texture promotes ductility.
