Abstract : In-situ straining experiments and post-mortem observations in a transmission electron microscope have been performed between 20 and 170C on Al-Mg-Si alloy 6056. Evidence is found for activation of cross-slip and occurrence of glide in the {001} planes. These mechanisms occur more readily as temperature increases. Their existence is discussed in the light of microstructural characteristics of the alloy and an attempt is made to correlate them with macroscopic properties.
