of the plate is, the more likely the recovery rather than the recrystallization occurs. This is the possible reason for the unnegligible difference in strength near the central region (Layer 4 and Layer 5). Key words: aluminum alloy thick plate; mechanical properties; inhomogeneity; fibrous grains; dynamic recovery; dynamic recrystallization 1 Introduction Aluminum alloys are widely used in aerospace......

dynamic materials test machine. The microstructures of the alloy were analysed with optical microscope and transmitted electron miroscope. The results show that the alloy only dynamic recovery occurred when the test temperature and strain rate of interest were 300-450 ℃ and 0.01-1 s-1; and the dynamic recrystallization was represented when the test temperature and strain rate of interest were 350-450......
