Mechanical and electrical conductivity of Cu-10Ti3SiC2/Cu-3GFs@Cu composites by heterogeneous laminated micro-nanostructure design

A heterogeneous laminated structure (HLS) design, complemented with an interlayer ordered structure (IOS), combined with heterogeneous powder gradient stacking (HPGS) and flake powder metallurgy (FPM) processes, results in the construction of a heterogeneous laminated micro-nanostructure (HLMS) with HLS and IOS of Cu/Ti₃SiC₂/C composites. Systematic investigation was conducted to explore the sources and contributions to improve the strength and resistance of the composites. Under applied loads, the HLS and IOS work synergistically. The refined grain orientation within the HLS reinforces the non-uniform deformation at interfaces, facilitating the interaction between strain gradients and geometrically necessary dislocations (GND), thereby enhancing energy absorption or dissipation during fracture. Meanwhile, the highly aligned reinforcement particles (RP) in the IOS help coordinate plastic deformations, reduce local stress concentrations, and optimize electron transport pathways to improve their performance. Results corroborate the assertion that this innovative HLMS structure design strategy is a highly valuable approach for the development of hetero-structured materials.

期刊介绍： Composites Part A: Applied Science and Manufacturing is a comprehensive journal that publishes original research papers, review articles, case studies, short communications, and letters covering various aspects of composite materials science and technology. This includes fibrous and particulate reinforcements in polymeric, metallic, and ceramic matrices, as well as 'natural' composites like wood and biological materials. The journal addresses topics such as properties, design, and manufacture of reinforcing fibers and particles, novel architectures and concepts, multifunctional composites, advancements in fabrication and processing, manufacturing science, process modeling, experimental mechanics, microstructural characterization, interfaces, prediction and measurement of mechanical, physical, and chemical behavior, and performance in service. Additionally, articles on economic and commercial aspects, design, and case studies are welcomed. All submissions undergo rigorous peer review to ensure they contribute significantly and innovatively, maintaining high standards for content and presentation. The editorial team aims to expedite the review process for prompt publication.
