Prediction of the Effect of Alloying Elements on In Situ Reaction in Synthesizing (AlN+Mg2Si)/Mg Composites
Alloying additions have an important effect on in-situ chemical reaction 4Al+Si3N4=4AlN+3Si to synthesis (AlN+Mg2Si)/Mg composites. Using the Wilson equation and an extended Miedema model, the activity in a multiple-component system can be calculated，and then the Gibbs free energy can be calculated. In final, the influence of alloying element additions on the in-situ chemical reaction at high temperature is investigated from a thermodynamic viewpoint.
