Abstract:
A hard composite composition comprises a binder; and a polymodal blend of matrix powder. In an embodiment, the polymodal blend of matrix powder has at least one local maxima at a particle size of 30 μm or less, at least one local maxima at a particle size of 200 μm or more, and at least one local minima between a particle size of about 30 μm to about 200 μm that has a value that is less than the local maxima at a particle size of 30 μm or less.
