A penetrator comprising a layered composite of at least one high density metal and at least one reactive metal material such as a reactive metal. Unlike the bimetallic structures of the prior art, a penetrator made of a composite or an alloy has a uniform structure throughout. Thus, a penetrator formed, for example, of a high density metal and a reactive metal will have sufficient mass to penetrate steel plate, and upon striking the steel plate, provide a very substantial release of energy which would be seen to compare favorably to that obtained with a penetrator formed only of a high density metal or a penetrator formed only of a reactive metal, of the same size, launched at the same speed.

LOW COST PROCESSING TO PRODUCE SPHERICAL TITANIUM AND TITANIUM ALLOY POWDER
Low cost spherical titanium and titanium powder alloy powder is produced by impinging a stream of an inert gas, such as argon, on the surface of a molten pool of titanium or sponge and alloying elements.
B22F 9/06 - Fabrication des poudres métalliques ou de leurs suspensions; Appareils ou dispositifs spécialement adaptés à cet effet par des procédés physiques à partir d'un matériau liquide
The present invention provides a reusable mandrel and method of using the mandrel in a SFFF process. A thermally conductive feature is located on the surface of the mandrel. The mandrel does not bond to the deposited part so that it may be easily removed without damaging either the mandrel or the deposited part. The present invention further enables the manufacture of components where the deposition surface is produced to precision, net shape geometries.
A method for producing porous materials which comprises directing a plasma stream containing particles of a base material in liquid or solid/liquid form onto a substrate under controlled conditions in which the particles spot weld to the substrate or to one another without full fusion, and establishing relative movement between the plasma stream and the substrate whereby the material is deposited as a porous structure of desired porosity and shape.
A reduced-weight container or vessel for storage, transportation and processing gases and liquids under pressure has a plurality of hollows formed in the outer wall, resulting in a reduced weight without compromising the structural integrity.

A COMPOSITE ARMOR TILE BASED ON A CONTINUOUSLY GRADED CERAMIC-METAL COMPOSITION AND MANUFACTURE THEREOF
A cermet armor material for highly effective ballistic performance which is comprised of a layer of base metal in which is deposited a layer or layers of ceramic and a compatible metal such that the deposited metal in combination with the base metal forms a continuous matrix around the ceramic particles. The body has a structure which is continuously graded from a highest ceramic content at the outer surface (strike face) decreasing to zero within the base substrate, and contained no abrupt interfaces.

CONTINUOUS PRODUCTION OF TITANIUM BY THE METALLOTHERMIC REDUCTION OF TICL4
A method for production of titanium particles or other metal of interest by a metallothermic reduction reaction of TiCl4 or other metal chloride in a reaction zone which comprises conducting the reaction in a fluidized bed reaction zone, and recycling particles to the reaction zone to build up particle size.
A method for producing a pure metal M or metal alloy MxNy, of interest, which comprises electrolyzing a molten salt electrolyte of an alkali-metal or alkaline-earth metal halide AX or AX2, with an anode formed of graphite or made of a composite of a metal oxide of the metal of interest and carbon, to discharge the alkali or alkaline-earth metal A, at the cathode, and to discharge nascent chlorine gas at the anode, whereby to produce a halide of the metal of interest MXn and/or NXn, and metallothermically reducing the metal halide MXn and/or NXn either separately or combined, with the alkali or alkaline-earth metal A, obtained cathodically to produce the metal M or the metal alloy MxNy of interest in particulate form.
A method of material treatment in which the surface of a metal substrate is converted to a composite structure of the metal and its nitride or carbide utilizing a high temperature chemically active thermal plasma stream, and the product obtained from that method. The complex thermal plasma contains controllable additions of active gas, liquid or solid substances. The surface layer obtained is functionally graded to the substrate resulting in an excellent bond that resists delamination and spalling, and provides a significant increase in hardness, wear and erosion resistance, and corrosion resistance, and a decrease in coefficient of friction.

THERMAL AND ELECTROCHEMICAL PROCESS FOR METAL PRODUCTION
A method of winning a metal from its oxide ore by heating the ore in a partial vacuum or under an inert atmosphere in the presence of a reductant. The resulting product may be further reduced electrochemically to produce a purer metal. The ore is preferably a titanium oxide ore and the reductant carbon or graphite.
A process for manufacturing Ti alloy structures using a SFFF manufacturing process with a welding torch as a high energy source, which comprises using as a feed a feed wire made from Ti sponge and alloying powders, or forming a Ti alloy in-situ in the melt.
A fabrication technique is described for producing lighter weight and improved wear and erosion resistant gun barrels (10). The barrels (10) are produced in an unconventional manner from the inside bore to the outside diameter of the barrel (10) and combine a refractory metal, metal alloy, or ceramic composite inner liner (12) with a metal matrix composite (MMC) or titanium or other suitable high strength, lightweight metal or metal alloy outer shell. A unique aspect of the invention is that there is a compositional gradation from the liner (12) at the inside bore to the overwrap which extends to the outside diameter of the barrel (10). A process is also described to produce barrels (10) with a refractory metal liner with improved wear and erosion resistance by depositing the refractory metal on the ID of a pre-fabricated barrel (10).
