Abstract: Described are molds, dies and forming tools comprising: a) a heat exchanging body support member; and b) within the support member, a molding cavity portion formed by thermal spraying metallic particles to a desired configuration in the support member. Also described are methods of making a mold, die or forming tool comprising the steps of: a) providing a body support member having a controlled and designed porosity which permits the enhancement of the heat transfer ability of said mold, die or forming tool; b) configuring a surface of the support member to a desired cavity; and c) spraying particles to the configured cavity in the support member, thereby producing a mold, die or forming tool. Preferably, the materials of construction are metallic and are applied by thermal plasma spraying. The particles may also be ceramics, metal matrix composites, ceramic matrix composites, thermoplastic resins, thermoset resins, and composites based thereupon.
Abstract: A material handling apparatus for processing heated formed ferrous metal products and/or glass products made of a face centered cubic crystal intermetallic alloy of a metal aluminide having the property of withstanding repeated thermal cycling from ambient temperature to about 1600.degree. F. wherein the metal is selected from the group consisting of a group VIII metal of the Periodic Table. Also described is an aluminide roll that also is characterized as retaining its ultimate tensile strength at 1600.degree. F. of at least 75% of the tensile strength the roll had at ambient room temperature.
