Composite constructions having ordered microstructures |
摘要 |
Composite constructions of this invention comprise an ordered microstructure made up of multiple structural units that can be the same or different, and that comprise at least a first structural phase and a second structural phase. The first structural phase comprises a hard material that is selected from the group consisting of cermet materials, PCD, PCBN and mixtures thereof. The second structural phase is in contact with the first phase and comprises a material that is different than that selected to form the first structural phase. Additionally, the second structural phase is in contact with at least a portion of the first structural phase. Composite constructions of this invention can also have a multi-layer structures comprising two or more layers, wherein at least one of the layers comprises a composite construction having an ordered microstructure made up of the multiple structural units described above.
