Uranium alloys containing titanium, niobium, zirconium, and molybdenum are produced in batches weighing up to 800 kg and cast into ingots or final shapes. The processing techniques utilized depend upon the alloy composition and upon quality limitations. Unalloyed uranium and alloys containing titanium and molybdenum are normally produced by vacuum induction melting; however, these alloys can also be produced by vacuum arc melting if high purity is necessary. The U--2 Nb alloy is generally produced by induction melting unalloyed uranium with U--6 Nb alloy scrap. Large ingots of U--6 Nb and U--7.5 Nb--2.5 Zr are generally produced by vacuum arc melting. When some refining of the charge material is required, such as in the consolidation of U--7.5 Nb--2.5 Zr machine turnings, electroslag melting is often desirable. Details of the various alloys and their respective characteristics and processing procedures are discussed under each process category. 7 tables, 10 figures. (DLC)
