<p>A hard-faced article includes a wear-resistance element that has a precipitated hard phase and a non-precipitated hard phase that is different from the precipitated hard phase in composition. The precipitated hard phase and the non-precipitated hard phase are dispersed through a boron-containing metallic matrix. The precipitated hard phase includes a boride material. The wear-resistance element can include, by weight, less than 50% of the non-precipitated hard phase. The wear-resistance element can also include boron, carbon, chromium and silicon such that, by weight exclusive of the non-precipitated hard phase, a product of the amounts of boron, carbon, chromium and silicon is greater than 28 and less than 350 and the amount of chromium by weight is less than 15%. A method includes forming the wear-resistance element with the precipitated hard phase and the non-precipitated hard phase dispersed through the boron-containing metallic matrix.</p> |
