Bulk Metallic Glass Matrix Composites

Abstract:

Bulk metallic glass BMG forming alloys were used to synthesis metal matrix composites with the BMG as the matrix. The second phase in the composite is a refractory ceramic material e.g. tungsten-carbide or a heavy ductile metal e.g. tungsten and tantalum. Composites containing up to 80 reinforcement were fabricated and characterized with respect to mechanical properties. Dynamic deformation behavior of BMGtungsten composites was studied at ballistic impact velocities. The 13 BMGtungsten composite has potentially useful properties as a kinetic energy penetrator.
