Al-based composites reinforced with Mg58Cu28.5Gd11Ag2.5 glassy particles have been synthesized by powder metallurgy. Powder consolidation was carried out by uniaxial hot pressing at temperatures within the super-cooled liquid region of the reinforcement to take advantage of the viscous flow of the glassy particles. The composites have improved yield and compressive strength compared to the unreinforced Al matrix without deteriorating the plasticity of the material. The relationship between mechanical properties and structure of the composites was investigated and described through the modified shear lag and mixture models.
