Interactions of Refractory Metals With Active Gases in Vacua and Inert Gas Environments,e equivalent to vacua of approximately 10. to 10. torr. These interactions can be reduced by minimizing the surface-to-volume ratio of the metal and minimizing the degree of equilibrium disparity. Added control is gained by the use of barrier foil envelopes and the use of low-pressure CH. to neutralize the oxidizing gases.

The Less Common Refractory Metals (Rhenium, Technetium, Hafnium, Noble Metals),l usage of the less common refractory metals in applications which depend upon their high melting point is concerned, high cost and low availability preclude any radical changes in the near future. Instead, an orderly growth is indicated as research pinpoints the occasional unique benefits which can justify their very high cost.

Basic Strengthening Mechanisms in Refractory Metals,e varied to produce strengthening, and relevant illustrations are given. The general areas reviewed include: (a) strengthening by second phase particles, (b) solid solution strengthening, (c) strain hardening and grain size refinement, (d) retaining worked structures at high temperatures, (e) dynami

Interactions in Coated Refractory Metal Systems,ormed by surface alloying the substrate. Interaction between these various barrier layers and the substrate and atmosphere form the subject of this paper. Interactions discussed in detail include: expansion mismatch; interstitial sink effects; effect of coatings on mechanical properties; diffusion p
