摘要: Dynamic aging precipitation of Mg17Al12 phases in AZ80 magnesium alloy was studied by multi-directional forging (MDF) with decreasing temperatures from 410 to 300 °C. The results show that the morphology dynamically precipitated β-Mg17Al12 (formed during process) exhibited granular shape. During process, inhomogeneous dynamic result coexistence fine grains (with many phases) and coarse (without samples. area expands final temperature. inhomogenous Al content distribution Mg matrix leads non-uniform phase. These phase retards growth DRX grains, which turns formation MDF process temperature decreasing.
