ABSTRACT:
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.
