Microstructural investigation on Ti63.5Fe30.5Sn 6 and Mg72Cu5Zn23 alloys reveals that bimodal eutectic structure containing the synchronization of structural and spatial heterogeneities in the spherical lamellar entity homogeneously forms upon solidification. Furthermore, the bimodal eutectic Ti63.5Fe 30.5Sn6 and Mg72Cu5Zn23 alloys present the enhancement of both strength and plasticity at room temperature compared to the recently developed high strength Ti- and Mg-based alloys. This implies that the bimodal eutectic structure can be one of the effective ways to improve the plasticity of the high strength alloys.
