Book Description
This report summarizes the information generated since the middle of 1961 on the chemical, physical, and mechanical properties of refractory metals that are coated with oxidation-resistant coatings of advanced-experimental or commercial status. It is a supplement to DMIC Report 162, Coatings for the Protection of Refractory Metals from Oxidation, dated November 24, 1961. Recent data on specific silicide- and aluminide- type coatings for columbium, molybdenum, tantalum, and tungsten and their alloys reflect general advances in coating quality and performance, understanding of the behavior of coated systems, and more complete realization of the problems associated with the use of coated hardware.

Book Description
The Nb program is nearing completion of laboratory tory rolling studiory materials, *Heat resistant alloys, *Sheets, Niobium alloys, Molybdenum alloys, Tantalum alloys, Tungsten alloys, Titanium alloys, Zirconium alloys, Tungsten, Powder metallurgy, Electric arcs, Manufacturing methods, Mechanical proper ies, Forging, Heat treatment, Melting, Extrusion, Deformation, Hardness, Rolling mills, Processing. Identifiers: Floturning. The Nb program is nearing completion of laboratory tory rolling studies, and a single composition for larger scale rolling studies will be selected in the near future. In the Mo program, it has been shown that true hot forging of billets to sheet bar results in higher recrystallization temperatures of TZM and Mo-0.5Ti sheet than are obtained when normal forging temperatures are used. The Ta program is in the early stages of ingot production and primary breakdown fabrication of the Ta-30Nb-7.5V alloy. Three methods of fabricating W sheet are being investigated: rolling of powder-metallurgy billets, fabrication of arc-melted ingots, and floturning of cylindrical blanks. Properties obtained on both powdermetallurgy and arc-melted tungsten sheet compare very favorably. Evaluation of the formability of Mo-alloy sheet has been delayed until sheet is available from the production program. (Author).

Book Description
This report presents the highlights of what has been ascertained about the interactions of liquid and vapor sodium, NaK potassium, lithium, and cesium with solid materials of potential use in practical liquid-metal systems. Data for inclusion were selected by the authors on the basis of their practical utility to designers and research workers. There has been an accelerating interest in alkali metals as (1) coolants for fast-breeder nuclear reactors, (2) coolants in space power plants, (3) Rankine-cycle working fluids in high- temperature nuclear reactors, (4) propellants in ion-propulsion engines, (5) seeding materials in magnetohydrodynamic generators, (6) space-charge dissipating media in thermionic generators, and (7) high-temperature hydraulic fluids. Prominent among the liquid-metals research efforts are studies directed toward finding the best containment material for a given alkali under a given set of operating conditions.
