Abstract
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.

Key words
acoustic emission, Portevin-Le Chatelier effect, load control
