A continuous electrolytic process for the production of beryllium metal /

The continuous production of beryllium metal by low-temperature fused salt electrolysis into a continuously circulating mercury cathode has been demonstrated. The product is amenable to direct hot pressing or to powder preparation by distilling off the mercury. The production of pure beryllium chloride in good yield by direct chlorination of beryllium oxide has also been demonstrated.

An investigation of the slip-casting mechanism as applied to stainless steel powder /

The slip-casting technique, which is successfully employed in the ceramic industry, was utilized to produce sintered stainless steel components experimentally. The procedure used is described, along with an evaluation of the physical and mechanical properties of the samples produced. Specimens were made with properties comparable to those of wrought stainless steel and of cold pressed and sintered steel powder.

Consumable electrode arc-melting of cold-compacted thorium powder /

The consumable electrode arc melting of cold-compacted thorium powder has been developed to produce dense, clean and soft ingots which can be hot rolled without cracking. By using a water-cooled copper crucible, contamination has been prevented and resultant ingots cleaner than the original powder have been produced.

Nucleation of voids in metals during diffusion and creep /

Experimental evidence is presented which proves that voids formed during diffusion in brass are heterogeneously nucleated. The nuclei appear to be oxide particles, probably ZnO. When these are removed by re-melting, voids practically do not form upon subsequent dezincification. Brass which had been freed of void nucleation catalysts exhibited a considerably reduced tendency for grain boundary cracking during creep, and increased stress-rupture life.
