Implication

Randomized trial demonstrates enhanced mechanical properties in copper-graphene composites, indicating promising applications.

Key Points

  • The research aims to improve the mechanical properties of copper by incorporating a graphene network through a hybrid process.
  • Used powder metallurgy to create a three-dimensional graphene network in copper matrix.
  • Combined with high-pressure torsion for severe plastic deformation.
  • Evaluated microstructural characteristics focusing on grain size and boundaries.
  • Achieved a grain size of ~300 nm, resulting in a nanostructured composite.
  • Observed a significant increase in microhardness and reached a tensile strength of ~500 MPa at room temperature.
  • Enhanced load transfer and crack-bridging capabilities were attributed to the unique structural features of the graphene.
