    Abstract: PROBLEM TO BE SOLVED: To provide a method for fabricating a metallic article without any melting.SOLUTION: A metallic article (20) made of metallic constituent elements is fabricated from a mixture of nonmetallic precursor compounds of the metallic constituent elements. The mixture of nonmetallic precursor compounds is chemically reduced to produce an initial metallic material, without melting the initial metallic material. A consolidation process may be performed by a viable technology. A preferable technology includes hot isostatic press, forging, pressure forming and sintering, and container extrusion of the initial metallic material. The material is consolidated to produce the consolidated metallic article (20). The consolidation is preferably performed by hot isostatic press, forging, pressure forming and sintering, and container extrusion of the initial metallic material.

    Abstract: PROBLEM TO BE SOLVED: To provide an electroslag-cold hearth (ESCH) system for refining or producing a desired metal or metal alloy. SOLUTION: The system includes at least one cold hearth vessel (35) capable of holding a pool (44) of molten liquid metal and an overlying slag layer (40), and an ingot mold (36) laterally off-set from the cold hearth (35). A source of raw material, e.g., a feed electrode (34), is positioned above the cold hearth (35), and fed into the molten slag (40) in a refining operation. A flow-over dam (54) separates the ingot mold (36) from the cold hearth (35), preventing the flow of inclusions and other foreign bodies into the ingot mold. In some instances, a non-consumable electrode provides additional thermal energy to the slag. In the production operation, the metal source can be a salt from which the desired metal can be electrochemically extracted. Related methods for refining or producing metals such as titanium alloys are also described. COPYRIGHT: (C)2005,JPO&NCIPI
