Using a spark plasma sintering process, production of the bulk metallic glassy matrix composites with large-size ultra-high strength and enhanced plasticity has been carried out. Effect of the glassy alloy classification, microstructure, species of the crystalline particulates, fraction, particulate size, and distribution on the properties of the obtained composites was investigated. The improvement of plasticity of the fabricated bulk glassy alloy composites originates from the structural inhomogeneity caused by the particles inclusion. The additional particulates act as a resisting media causing deviation, branching and multiplication of shear bands.
