Acoustic emission (AE) has been used to study magnesium alloys for many years. The advantage of AE is getting the data from the entire volume with high time resolution. The determination of the source of AE is an important task. We use a new method of evaluation of the AE signal: Adaptive Sequential K-means (ASK) analysis and its advantages for studying mechanical and corrosion properties of magnesium alloys. It uses the discrete Fourier transformation and statistical approach to discriminate between the different sources of AE. The results are presented on mechanical tests of rolled AZ31 sheet with high texture and corrosion behavior of pure magnesium and WE43 magnesium alloy.Keywords: Magnesium, acoustic emission, mechanical testing, corrosion
