Large-size of Zr₅₅Cu₃₀Al₁₀Ni₅ glassy alloy composites (GACs) containing TiNb particles were fabricated by spark plasma sintering (SPS) process. Large plasticity and high strength were obtained due to addition of TiNb particles. Two kinds of TiNb particles with different particle size were introduced into glassy matrix. The GACs samples reinforced by smaller particles showed higher strength and larger plasticity. The GACs with the addition of TiNb particles exhibit similar thermal properties in comparison with the glassy matrix alloy. No other crystalline phase besides TiNb was detected in the composites and good bonding state between TiNb and glassy matrix was observed.
