摘要

Consolidated materials comprising a plurality of coated particles dispersed in a tough matrix material are disclosed. The coated particles include a plurality of core particles having an intermediate layer that substantially surrounds each of the core particles. An optional outer layer may be present on the intermediate layer. A matrix contains or substantially contains each of the coated particles, and is formed from at least one third compound including a mixture of W, WC, and/or WC with Co. The amount of Co in the at least one third compound may range from greater than 0 to about 20 weight %. Methods for providing consolidated materials, and articles comprising such consolidated materials are also disclosed.
