Abstract

In the present study, bulk metallic glassy composites (BMGCs) of Zr55Cu30Al10Ni5 glassy matrix reinforced by ductile TiNb particle and hard ceramic ZrO2 were fabricated by SPS successfully. The plastic strain of the BMG is enhanced due to addition of reinforcement. The effect of particle size, volume fraction and intrinsic mechanical properties of the reinforcements on the mechanical properties of BMGCs were studied. The results show that larger plastic strain is obtained for the BMGCs reinforced with smaller particle size. The plasticity of composite reinforced by TiNb particles is larger than that of composite reinforced by ZrO2. It results from that the initiation of shear band in the glassy matrix is related to the plastic strain misfit between the reinforcements and the glassy matrix. Thus, a larger macro-plasticity is obtained in the composites reinforced by TiNb particles.
