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 BMG/tungsten composites was studied at ballistic impact velocities. The 13 BMG/tungsten composite has potentially useful properties as a kinetic energy penetrator.
