It has been shown that the amount of β(Mg17Al12) intermetallic compound decreases by adding Ca and RE elements into AZ91 alloy and new Al11RE3 and Al2Ca intermetallic compounds form in the microstructure. The coarsening of

The results showed that the coarsening kinetics of the solid globular particles in semisolid slurry of AZ91 alloy satisfies the Ostwald ripening theory.
