Methods for making zirconium based alloys and bulk metallic glasses
Methods of preparing Zr based metallic using Zr sponge refined by a refining process are described. An exemplary method includes heating Zr sponge in a processing chamber with an electron-beam-heating apparatus or an arc-melting apparatus under a desired pressure condition to release volatile contaminants from the Zr sponge, introducing a purge gas into the processing chamber and permitting the purge gas to intermingle with at least some of the released volatile contaminants, evacuating the processing chamber to extract at least some of the purge gas and released volatile contaminants, repeating the heating of the Zr sponge, the introducing of the purge gas, and the evacuating of the processing chamber release and evacuate additional volatile contaminants from the Zr sponge to provide a processed Zr sponge with enhanced purity, and melting the processed Zr sponge with multiple other alloy constituents to provide a Zr-based metallic alloy.
Novel Synthetic Rutile Products and Processes for Their Production
This invention relates broadly to the production of titanium alloys by electrolytic reduction processes, and is concerned in one or more aspects with the preparation of a feedstock for such processes. In other aspects, the invention relates to a novel synthetic rutile (SR) product and to methods of producing titanium alloy from titaniferous material.

Iron and molybdenum containing agglomerates
Iron and molybdenum containing agglomerates and a process for producing the agglomerates are disclosed. A green agglomerate is produced from mixing an iron containing powder, a molybdenum oxide powder, and a carbonaceous powder. The green agglomerates can be reduced at a temperature in the range of 400-1500 C.
