Abstract Crystallographic calculation based on the edge-to-edge matching model predicted that both TiB2 and Al3Ti intermetallic compounds have strong potential to be effective grain refiners for beta phase in the Mg-14Li-1Al alloy due to the small atomic matching misfit across the interface between the compounds and beta phase. Experimental results showed that addition of 1.25 wt%Al-5Ti-1B master alloy reduced grain size of beta phase in the alloy from 1750 to 500 mu m. The possible grain refining mechanisms were also discussed
