摘要： A method of production of large Ingots of neutron attenuating composites using a vacuum-bellows system allows for large cross-sectional shapes to be extruded and rolled. A vacuum-bellows technology which allows the manufacturing of large diameter ingots. A variety of primary metal matrix materials can be used in this technology. High specific strength and stiffness can be achieved because the technology allows for final densities of 99% and higher. The vacuum-bellows technology allows metals and ceramics to blend and mesh together at compression pressures of 800 tons with elevated temperatures. The controlled compression movement allows for any oxide layer, on the metal, to be broken up and consolidated with the chosen ceramic particulate. By controlling the amount of boron-rich ceramics, by volume or weight, certain B-10 isotope areal densities can be accomplished. These B-10 isotopes attenuate neutrons in nuclear fuel. Other elements, which have high, cross-sectional Barn values can be used.

摘要： Metallurgical powder compositions are provided that include silicon carbide to enhance the strength, ductility, and machine-ability of the compacted and sintered parts made therefrom. The compositions generally contain a metal powder, such as an iron-based powder, that constitutes the major portion of the composition. A silicon carbide-containing powder is blended with the metal powder, preferably in the form of a silicon carbide powder. Optionally, common alloying powders, lubricants, binding agents, and other powder metallurgy additives can be blended into the metallurgical composition. The metallurgical powder composition is used by compacting it in a die cavity to produce a nullgreennull compact that is then sintered, preferably at relatively high temperatures.

摘要： A method for making a high density powdered metal article is provided. The composition consists of iron based powder, lubricant, graphite and ferro alloy additions. The composition is compacted in rigid tools at ambient temperature, sintered at high temperature and then formed in rigid tools at 40 to 90 tons per square inch to a density greater than 94% of theoretical. The high density article is then annealed. The final article demonstrates remarkable mechanical properties which are atypical of powdered metal components and approach those of wrought steel.
