Overview

Randomized trial demonstrates improved mechanical performance in SiCp/Al composites, indicating the importance of interfacial compatibility.

Key Points

  • This research aims to enhance the mechanical properties of SiCp/Al composites by improving the interfacial compatibility through pre-oxidized silica-rich interlayers.
  • Engineered SiC/Al interface by pre-oxidizing SiC to create silica-rich interlayers.
  • Assessed mechanical performance including ductility, toughness, and tensile strength.
  • Utilized a composite with a SiO2-rich layer thickness approximately 128 ± 9 nm.
  • Ductility improved by 18.3% and toughness by 15.4% compared to unoxidized counterparts.
  • Ultimate tensile strength maintained at 259.9 ± 4.1 MPa.
  • Enhanced interfacial compatibility increased interfacial strength and delayed strain localization.
