摘要	The paper presents a novel porous, ductile, V particles reinforced, Mg-based metallic glass composite, exhibiting superior mechanical performance with up to 10% compressive strain and 1100 MPa stress at room temperature. Indentation tests show that the addition of V particles can improve significantly the plastic deformation ability of the glass composites in local regions around the particles. Furthermore, during deformation process, the highly localized shear-banding of the infiltrated glassy matrix within the porous V particles induces an increase in temperature in local regions, where the dilating and softening behavior happen. The heated V particle regions become more effective "sites" for the initiation and arrest of shear bands in the surrounding amorphous matrix. We suggest that porous ductile particles might therefore preferably be used to toughen amorphous materials with stubborn brittleness.
