The detailed microstructural investigation clearly reveals that the Bi was highly saturated at the colony boundary of the ultrafine eutectic alloys. The chemical heterogeneity introduced by the additional Bi in the present investigation effectively dissipates the localization of the stress thus improving the plasticity up to 8.5% without compromising the strength of 2100 MPa.
