Simultaneously enhanced strength and ductility of copper composites by tailoring the intragranular carbonized polymer dots distribution
R Bao, H Luo, L Liu, J Yi, J Tao, C Li - Composites Communications, 2023 - Elsevier
Distribution states of reinforcement have considerable impact on the strength and ductility of
metal composites. Herein, we reported a “nanodispersion-in-grains” strategy to
simultaneously strengthen and stabilize Cu composites, which relied on a uniform
dispersion of extremely fine carbonized polymer dots (CPD) inside grains. The intragranular
CPD distribution not only elevated the strength of pure Cu by∼ 45%, but also activated
hardening mechanisms via dislocation-nanoparticle interactions. Meanwhile, 0.2 wt …
