Abstract
A metal-matrix composite tool includes a matrix region. The matrix region has a reinforcement material, an outer surface, and an inner, localized area spaced apart from the outer surface within the reinforcement material. The reinforcement material has a reinforcement density and the localized area has a localized density different from the reinforcement density. The matrix region has an overall matrix density different from both the reinforcement density and the localized density.
Claims20
A metal-matrix composite tool, comprising:
- a matrix region including a reinforcement material, an outer surface, and an inner, localized area that does not intersect the outer surface of the tool, wherein the outer surface surrounds the reinforcement material and the localized area,
- wherein the reinforcement material has a reinforcement density, the localized area has a localized density different from the reinforcement density, and the matrix region has an overall matrix density different from both the reinforcement density and the localized density, wherein the localized area includes an insert that includes an outer surface configured to prevent migration of the insert within the reinforcement material or to provide mechanical interlocking of the insert with the reinforcement material, wherein the insert includes a grid or lattice.
