This report summarizes information on refractory composites for use above 2500 F, as presented at the Seventh Meeting of the Refractory Composites Working Group, held March 12-14, 1963. Reports presented at the meeting were concerned with pro tective coatings, insulating ceramics, materials for rocket thrust chambers, dispersion strength ening of metals, joining of refractory materials, and testing techniques. Emphasis in the field of coatings for refractory metals has shifted from the rudiments of developing oxidation-resistant coatings to improvement and advanced evaluation of coatings to predict their utility for re-entry vehicles.

The Welding and Brazing of Alloy 718

| Genre | : Nickel alloys |
| ISBN | : |
Because of a special interest in Alloy 718, the Defense Metals Information Center has summarized information on the welding and brazing of the alloy. Two principal resons for the interest in this alloy are its good formability and its good weldability, expecially under restraint. The greater portion of the fusion welding of Alloy 718 has been done by the gas tungsten-arc (TIG) process. A discussion of welding atmosphere, filler metals, heat treatment of welds, welding under restraint, and weld toughness is presented in the section on fusion welding. Information is also presented on resistance welding and electron-beam welding of Alloy 718. The final section of this report deals with the brazing of Alloy 718.

This report describes the evaluation of candidate materials systems for high temperature service and is presented in two separate parts: the first pertains to the development of laboratory tests for the evaluation of refractory alloy coatings; the second, to the arc-plasma-jet evaluation of ablative materials, impregnated porous ceramics, refractory composites, and sprayed ceramic coatings. Part I describes analytical and experimental approaches leading to the development of an orderly series of tests designed to characterize the oxidation behavior of refractory alloy coatings and to determine their influence upon the physical and mechanical properties of the base metal. Part II describes the screening of 78 different high temperature materials with an arc-plasma-jet testing facility. The systems evaluated fell into four general categories: ablative materials, impregnated porous ceramics, refractory composites, or sprayed ceramic coatings. Testing procedures were adjusted for each class of materials to emphasize particular performance characteristics. (Author).

This report is the third of a series which will periodically summarize the status of the various contracts involved in the Department of Defense Refractory Metals Sheet Rolling Program. Under this program, selected candidate materials are being carried through one or more of the following consecutive phases: Phase I, development of a sheet-production practice; Phase II, establishment of minimum design data; and Phase III, evaluation of sheetfabrication characteristics. To the present time, 13 contracts have been funded or planned in support of the Phase I, II, and III activities. This report summarizes the status of each of these individual contracts as of November 1, 1964. The first section describes the overall program of the Department of Defense Refractory Metals Sheet Rolling Program. Following, in the order of their discussions, are sections dealing with fabricable molybdenum alloys, unalloyed tungsten, columbium alloys, and tantalum alloys. (Author).
