This report summarizes the achievements on fourteen programs that were conducted in support of the Metals Sheet Rolling Program. These included programs for developing practices to produce large sheets from two grades of unalloyed tungsten (via powder metallurgy and arc melting, respectively), as well as for the Mo-0.5Ti, Mo-0.5Ti-0.1Zr-0.03C (TZM), Cb-10W-1Zr-0.1C (D-43), Cb-10W-2.5Zr (Cb-752), and Ta-30Cb-7.5V alloys. In addition, pilot sheet-rolling programs were also carried out for the Cb-27Ta-10W-1Zr (FS-85), Cb-5Mo-5V-1Zr (B-66), Ta-7W-3Re (GE-473), and Ta-9.6W-2.4Hf-0.01C (T-222) compositions.

This report covers deposition of refractory pure metals and alloys using the Directed Light Fabrication (DLF) process and represents progress in depositing these materials through September 1998. In extending the DLF process technology to refractory metals for producing fully dense, structurally sound deposits, several problems have become evident. (1) Control of porosity in DLF-deposited refractory metal is difficult because of gases, apparently present in commercially purchased refractory metal powder starting materials. (2) The radiant heat from the molten pool during deposition melts the DLF powder feed nozzle. (3) The high reflectivity of molten refractory metals, at the Nd-YAG laser wavelength (1.06[micro]m), produces damaging back reflections to the optical train and fiber optic delivery system that can terminate DLF processing. (4) The current limits on the maximum available laser power to prevent back reflection damage limit the parameter range available for densification of refractory metals. The work to date concentrated on niobium, W-25Re, and spherodized tungsten. Niobium samples, made from hydride-dehydride powder, had minimal gas porosity and the deposition parameters were optimized; however, test plates were not made at this time. W-25Re samples, containing sodium and potassium from a precipitation process, were made and porosity was a problem for all samples although minimized with some process parameters. Deposits made from potassium reduced tungsten that was plasma spherodized were made with minimized porosity. Results of this work indicate that further gas analysis of starting powders and de-gassing of starting powders and/or gas removal during deposition of refractory metals is required.
