Abstract

The kinetics and microstructure of the discontinuous precipitation in Mg-7 wt. % Al has been investigated at different temperatures and time, using the Differential Scanning Calorimetry (DSC), X-ray diffraction, microhardness measurement and optical microscopy. In this paper, we employed methods for calculation of the activation energy, volume fraction and mechanism of precipitation of new phase γ(Mg17Al12). At 150°C accelerate relatively the diffusion process and the S- mechanism is more dominating in discontinuous precipitation.
