    摘要： An infiltration method of forming an article including providing a working mold including a solid binder member extending through an interior of the working mold, wherein the solid binder member is made of a binder material, and providing a layer of powder matrix material within a molding void of the working mold. The method further includes heating the working mold to form a molten binder pathway from the solid binder member to infiltrate the layer of powder matrix material.

    摘要： A system for casting comprising a mold for forming molten metal; a support for supporting the mold and transferring heat to and from the mold; and a furnace operable to substantially surround the mold through a preheat cycle, a heat cycle, and a cooling cycle. The furnace preferably moves vertically down to surround the mold for the preheat, heat, and cooling cycles and moves up and away from the mold after the cooling cycle is complete. In an alternative embodiment, the furnace may be replaced with a cooling can just before initiation of the cooling cycle. The support is preferably stationary and provides directional cooling for the mold during the cooling cycle.
