ABSTRACT:
A cast metal article, such as a turbine engine component, is made by shaping a body of refractory metal particles to form a molded refractory metal article. The molded refractory metal article is sintered to form a refractory metal core. Both the refractory metal article and a setter block may be sintered at the same time. At least a portion of the refractory metal core is enclosed with wax. The wax is at least partially enclosed with a covering of mold material. The wax is removed from the mold material to form an article mold cavity. The article mold cavity is filled with molten metal which solidifies to form a cast metal article. The refractory metal core is removed from the cast metal article.
