Orientation effects on acoustic emission during tensile deformation of hot rolled magnesium alloy AZ31

Acoustic emission (AE) is observed during tensile testing of commercial AZ31 magnesium sheets in different temper conditions. Tests were conducted in rolling direction (RD) and transverse direction (TD), respectively. The results are discussed with respect to the crystallographic texture and the microstructure in terms of the orientation-dependent activation of different deformation mechanisms like dislocation glide and twinning.
