Wrought magnesium alloy AZ31 was pre-compressed and subsequently subjected to tensile loading. Due to a strong fibre texture of the alloy the level of pre-compression stress significantly influences the following tensile test.
The results of acoustic emission (AE) measurement are correlated with the stress-time curves and differences in the AE count rate were used to reveal changes in underlying deformation mechanisms.
