Abstract
A metal matrix composite tool that includes a hard composite portion comprising a reinforcement material infiltrated with a binder material, wherein the reinforcement material comprises a refractory metal component dispersed with reinforcing particles, wherein a surface roughness of the reinforcing particles is at least two times greater than the refractory metal component, wherein the refractory metal component has a failure strain of at least 0.05 and a shear modulus of 200 GPa or less, and wherein the reinforcing particles have a failure strain of 0.01 or less but at least five times less than the failure strain of the refractory metal component, and the reinforcing particles have a shear modulus of greater than 200 GPa and at least two times greater than the shear modulus of the refractory metal component. The reinforcing particles may comprise an intermetallic, a boride, a carbide, a nitride, an oxide, a ceramic, and/or a diamond.
