Fabrication, microstructure, and properties of (NbTi)C particle-reinforced copper matrix composites

Optimization of fine-grained powder addition for strengthening and wear resistance in heterostructured 2219 Al alloys fabricated by powder metallurgy

High-performance 2219 Al-Cu alloys are urgently required for lightweight aerospace structures, yet conventional powder metallurgy alloys often show limited strength–ductility synergy and inadequate wear resistance. In this study, heterogeneous grain-structured 2219 Al-Cu alloys were fabricated by introducing differen...

Preparation, microstructure and properties of copper-coated flake graphite and SiC particles hybrid reinforced aluminum matrix composites

Metal matrix composites with outstanding tribological performance and balanced mechanical and thermal properties have great potential for applications in lightweight wear-resistant components and precision machinery. In this work, we present an effective strategy for fabricating copper-coated flake graphite and SiC p...
