From: Microstructure and mechanical behavior of metallic glass fiber-reinforced Al alloy matrix composites
(a,b) SEM micrograph of the lateral surface of the deformed composite material (after fracture), the inserted schematic diagrams show the morphology of the composite during compression, the black circles represent large glassy particles, the white matrix represents the Al7075 + nanoscale glassy fibers, the black curves represent the cracks which are along the maximum shear stress direction, the black dash lines represent the deformation bands due to plastic deformation in the matrix. (c) SEM micrograph of the fracture surface of the composite after failure. (d) SEM-EDX mapping of area marked by a red rectangle in (c), which indicates that the bright area is glassy reinforcement (rich in Zr element and poor in Al, Mg and Zn), the spots marked by white arrows are MgZn2 precipitates (rich in Mg and Zn).
