Abstract:
1. A composite construction having an ordered arrangement of first and second material phases, the construction being formed by the process of: combining one or more precursor materials selected from the group consisting of ceramics, metals, diamond, cubic boron nitride, and mixtures thereof to form a green-state first material phase part; combining one or more materials selected from the group consisting of ceramics, Co, Ni, Fe, W, Mo, Cu, Al, Nb, Ti, Ta, and alloys thereof to form a green-state second material phase part, wherein one of the first or second material phase parts does not include a ceramic material; joining together a number of the first and second green-state material phase parts to form a green-state assembly, wherein at least one of the first and second green-state material phase parts are commonly oriented within the assembly; and consolidating and sintering the green-state assembly at high presssure/high temperature conditions to form the composite construction.
