摘要	Replacing parts of a solid with voids usually weakens a material. Here, we report that a material (Au-Pt-Ag alloy) becomes stronger by 7 times, its strength increases from 50 to 345 MPa, when approximate to 40% of solids (Ag) is dissolved and replaced by pores during dealloying. The corrosion-induced strengthening originates from the formation of nanoporous structure, and the high strength of nanoscale ligaments due to size effect. The results also suggest that the connectivity of nanoporous structure decreases during coarsening, leading to additional decreases in strength and stiffness, which may explain the unexpected low strength and stiffness of previously reported nanoporous gold.
