Acoustic emission (AE) was observed and analysed during PLC (Portevin-Le Chatelier) plastic instabilities in tests under load rate control. Results of the load rate controlled and former cross-head speed controlled tests are compared. Duration of the AE events increased at the beginning of plastic deformation, however, the events remained separated throughout the tests.
