Recent Advances in Columbium Alloys,trength and good ductility and that are readily fabricable and weldable are commercially available. These alloys were the first of the columbium base alloys to receive serious consideration for use in components on actual flight systems. Emphasis in the development of new columbium alloys over the p

The Less Common Refractory Metals (Rhenium, Technetium, Hafnium, Noble Metals),tallurgy of rhenium and of technetium, an artificial element which has only recently become available in sufficient amount for metallurgical studies to be possible, are surveyed. New data on phase equilibria, mechanical and physical properties and availability are included. Special attention is also

Interactions in Coated Refractory Metal Systems,roblems that control coating life; and metallic claddings. Methods to solve the complex interaction effects are discussed and illustrated by low temperature oxidation problems of refractory silicide coatings, crack arresting effects of porosity in coatings, coatings containing a molten phase, and low pressure effects.
