Abstract Scope Metallic glass (MG)-reinforced Al matrix composites are an emerging new class of composite materials. The metallic nature and the high mechanical strength of MG offers unique possibilities for improving the engineering performance of composites. This talk attempts to shed light on understanding the structure-property correlation of these composites. Here micro and nano-sized metallic glassy particles, short fibers and nanocrystal particles devitrified from metallic glasses have been introduced in aluminum alloy matrices by ball milling and sintering. The addition of MG reinforcements significantly improves the mechanical behavior of the composites. High-resolution TEM observations at the interface reveal the formation of a thin inter-diffusion layer able to provide good bonding. Furthermore, the findings will be discussed with respect to a critical analysis of the different factors contributing to the strength of the composite. The findings may offer new options to develop metal matrix composites reinforced with metallic glasses.
