Using a mixed powder of argon gas-atomized Zr<SUB>55</SUB>Cu<SUB>30</SUB>Al<SUB>10</SUB>Ni<SUB>5</SUB> metallic glassy alloy powder blended with 10 vol% ZrO<SUB>2</SUB> powder, Zr<SUB>55</SUB>Cu<SUB>30</SUB>Al<SUB>10</SUB>Ni<SUB>5</SUB> bulk metallic glassy matrix composite was fabricated by a spark plasma sintering process. The structure, thermal stability and mechanical properties of the sintered bulk metallic glassy matrix composite were investigated. The ZrO<SUB>2</SUB> particles were homogeneously dispersed in the Zr<SUB>55</SUB>Cu<SUB>30</SUB>Al<SUB>10</SUB>Ni<SUB>5</SUB> glassy matrix. No crystallization of the glassy matrix occurred during the spark plasma sintering process. The crystallization behavior of the sintered composite was similar to that of the metallic glassy powder. The sintered composite specimen exhibited larger plastic ductility than that of the as-cast Zr<SUB>55</SUB>Cu<SUB>30</SUB>Al<SUB>10</SUB>Ni<SUB>5</SUB> glassy alloy rod specimen. The increase in the plastic ductility is proposed to originate from the structural inhomogeneity caused by the ZrO<SUB>2</SUB> ceramic particles.
