| Abstract Scope |
The activity of individual deformation mechanisms which occur during tensile loading of Mg-Al-Mn sheets was investigated using the acoustic emission (AE) technique. The investigated sheets exhibited a typical basal texture with basal planes oriented nearly parallel to the rolling direction. Tensile tests were performed at room temperature and deformation behavior was analyzed by digital image correlation (DIC). The obtained results were supported by microstructure evolution analysis provided by electron backscattered diffraction (EBSD). The AE signal analysis correlated the microstructure and the stress-strain curves to the active deformation mechanisms quite well. To determine the dominant deformation mechanism in a given time period, the adaptive sequential k-means (ASK) clustering was applied. |
