Overview

Randomized trial investigates the interfacial strengthening mechanism in aluminum composites, suggesting insights for design improvements.

Key Points

  • This study aims to clarify the micromechanical behavior and strengthening mechanisms at the reinforcement/matrix interface in aluminum composites.
  • SiC particle-reinforced 2024 Al matrix composites were fabricated using vacuum hot-press sintering.
  • Comprehensive microstructural characterization was conducted to analyze the orientation relationship at the SiC/Al interface.
  • Molecular dynamics simulations studied deformation mechanisms under tensile loading.
  • The interfacial bonding exhibited a high yield strength and significant sustained plasticity.
  • Plastic deformation was primarily governed by stair-rod dislocations, with notable triangular-pyramidal dislocation locks formed.
  • Crack nucleation and propagation initiated in the near-interface region, promoting ductile fracture behavior.
