Abstract
A hard metal composite is formed from a mixture of two or more pre-blended, unsintered hard metal composites in which the properties of each constituent are different.
The constituent components are selected so that they have different grain sizes, different binder contents, different metal carbide or binders, or some combination of these. Primarily, the constituents are chosen on the basis of their properties and compatability, and are chosen to utilize the superior properties of one of the constituents without detrimentally affecting the desirable properties of the other. As an example, a pre-blended composite having a superior hardness may be dispersed in a second composite having a superior toughness with the resultant material having a hardness which approaches that of the harder constituent yet maintaining the toughness of the matrix constituent.
