Abstract

A mass of metal powder is compacted about a core of uranium metal, the powder and the core being at a temperature above the beta - gamma transition point of uranium. The powder may be beryllium, zirconium, molybdenum, tungsten, titanium, tantalum, niobium, iron, copper, brass, bronze, or alloys of aluminium or beryllium; preferred powders being beryllium, zirconium or a mixture of beryllium and aluminium. Thus, a layer of beryllium powder is placed in a mould, a bar of uranium is placed on the layer and more beryllium powder is filled into the mould, the uranium bar being centrally located in the powder. The powder is then thoroughly impregnated with hydrocarbon oil to displace air. The contents of the mould are then compressed by dies at 10 tons p.s.i., and heated to 800 DEG C. by electrical heating elements associated with the mould or by passage of current through the contents of the mould by way of the dies. The die compression members may be grooved or slotted to form ribs or fins on the sheath, and the die may be of "Nimonic" (Registered Trade Mark) nickel-chromium alloy or of nickel-titanium carbide.ALSO:A mass of metal powder is compacted about a core of uranium metal, the powder and the core being at a temperature above the beta-gamma transition point of uranium.

The atmosphere provided by vaporization of the hydrocarbon oil protects the metals from atmospheric attack. The die compression members may be grooved or slotted to form ribs or fins on the sheath.
