The paper presents the resultsof invastigations of the correlations occuring between the rate of the acoustic emission )AE) events and the plastic deformation mechanism during the plane strain compression of pure magnetism and magnesium-lithium as well as magnesium-lithium-aluminium alloys. Essential qualitative and quantitative defferences in the AE behaviour have been observed between the pure magnesium and alloys as well as between the alloys themselves. The obtained results are discussed on the basis of the possible dislocation and work-hardening processes and also on the basis if microstructure observations using the light microscopy.
