摘要
The kinetics of discontinuous precipitation of Ag2Al intermetallic in alloy Al - 10% Ag is studied after 10-h holding in vacuum at 530 degrees C and subsequent water quenching. The DSC and dilatometric curves are plotted for heating rates ranging from 5 to 20 K/min. The activation energy of formation of the Ag2Al -phase is computed from the DSC data with the help of the Boswell equation and by the Kissinger method.
