    摘要： The invention relates to methods of preparing cutting inserts for earth-boring bits. In one embodiment the method comprises partially filling a mould with a first cemented hard particle powder, filling at least a portion of the remaining portion of the mould with a second cemented hard particle powder, consolidating the first and second cemented hard particle powders into a single green compact and sintering the single green compact. In a further embodiment the method comprises consolidating a first cemented carbide powder in a mould to provide a first green compact, placing the first green compact in a second mould, wherein the first green compact fills a portion of the second mould, filling at least a portion of a remaining portion of the second mould with a second cemented carbide powder, consolidating the second cemented carbide powder and the first green compact together to form a second green compact and sintering the second green compact.

    摘要： Embodiments of the present invention include composite articles comprising at least a first region and a second region and methods of making such articles. The first region may comprise a first composite material, wherein the first region comprises less than 5 wt. % cubic carbides by weight, and the second region may comprise a second composite material, wherein the second composite material differs from the first composite material in at least one characteristic. The composite article may additionally comprise at least one coolant channel. In certain embodiments, the first and second composite material may individually comprise hard particles in a binder, wherein the hard particles independently comprise at least one of a carbide, a nitride, aboride, a silicide, an oxide, and solid solutions thereof and the binder comprises at least one metal selected from cobalt, nickel, iron and alloys thereof. In specific embodiments, the first composite material and the second composite material may individually comprise metal carbides in a binder, such as a cemented carbide.
