Abstract

Microstructural investigation on Ti_63.5Fe_30.5Sn 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 Ti_63.5Fe _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.
