DOWNLOAD EBOOKA summary is presented of the status of the Department of Defense Refractory Metals SheetRolling Program to accelerate the development of production techniques for high-quality, consistent sheet products from the refractory metals (Nb, Mo, Ta, and W) and their alloys. The program includes: (1) development of sheet production techniques, (2) establishment of minimum data re uired to evaluate mill production, (3) evaluation of fabrication characteristics of the sheet produced, and (4) establishment of design data. Contracts were awarded for the development of sheet production techniques for all four refractory metals. One contract was awarded for the evaluation of Mo alloy sheet fabrication characteristics.

DOWNLOAD EBOOKThis 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.

DOWNLOAD EBOOKA system has been developed for determining the conventional mechanical properties of materials at temperatures up to 4000 F in vacuum. Techniques for obtaining stress-strain properties in tension and compression are described in this report. Strains are measured optically directly at the gate section to an accuracy of plus or minus 50 microinches per inch in a 2-inch gage section. An evaluation of the system was made using a Mo-0.5Ti bar material. Exploratory work was conducted on graphite and a refractory sheet metal. The results for these tests are included in the report. With the objective of developing a temperature source for use above 4000 F, experiments were conducted to produce and to evaluate tantalum carbide-coated graphite heaters. Good coatings of tantalum carbide were produced both on thin-wall cylindrical heaters and on spiral heaters. It was found that carbon contamination of the atmosphere occurred such that tungsten shields of tungsten specimens were attacked at temperatures under 5400 F. Possible means of improving carbide coatings are suggested.
