A wear-resistant member (20) that includes a hard composite member (24) affixed to a support (22). The hard composite member (24) includes discrete hard constituents (34) distributed therein. Each one of the discrete hard constituents (34) has a surface area between about 0.001 square inches and about 16 square inches. The hard composite member (24) further contains a matrix powder (30) that includes particles wherein substantially all of the particles have a size smaller than the size of the hard constituents. The hard constituents (34) and the matrix powder (30) are bonded together by an infiltrant alloy (31) to form the hard composite member (24). The support (22) is made of a material that bonds with the infiltrant alloy (31).
