This paper reported the effects of Al-5Ti-B-2RE on the microstructures and mechanical properties of an Al-10Mg alloys. It has been shown that the addition of 6wt.% Al-5Ti-B-2RE alloy can decrease the average grain sizes and increase the mechanical properties of the Al-10Mg alloy. Grain refinement mechanism is due to TiAl3 andTiB2 particles formation nucleation of aluminum,rare earth elements enhancing the kinetics of α-Al nucleation and inducing low growing speed of crystals. And the grain refinement strengthening and dispersion strengthening lead to improve the mechanical properties.
