Abstract

The rolled sheet of AZ31 with the strong basal texture in ND direction was used for this study. Three different sample orientations (ND, 45, RD) were cut out and deformed in compression and tension. The acoustic emission (AE) was measured during the deformation and the deformed microstructure was studied by the electron backscatter diffraction. The advanced analysis of the AE measurements provides an insight to the active deformation mechanism. Extension twinning plays an important role in the deformation behavior. The higher yield stress can be observed when the texture is unfavorable oriented for twinning. Moreover, another twinning system has been observed to be active in such oriented samples.
