Abstract
Optical, scanning and transmission electron microscopy techniques have been used to characterize the fiber-matrix interfaces in P100Gr/AZ91C Mg composites fabricated by diffusion-bonded and vacuum investment casting methods. Fiber-matrix interface regions in composites prepared by both methods showed good bond, no voids and absence of any interfacial reaction. The quantitative analysis by energy dispersive spectroscopy of matrix regions between fibers, showed aluminum rich areas adjacent to the fiber-matrix interface and solute poor regions in interfiber spaces in both diffusion-bonded and cast Gr/Mg composites. A qualitative assessment of dislocation substructure in the matrix region near the fiber-matrix interface, suggests a lower residual stress state in cast composites than diffusion-bonded composites.
