## Abstract Adding small amounts of Si or Ga (3 at.%) to the eutectic Al~83~Cu~17~ alloy yields an ultrafine bimodal eutectic composite microstructure upon solidification. The as‐solidified alloys exhibit a distinct microstructural length‐scale hierarchy leading to a high fracture strength of aroun
