The Metallurgy and Ceramics research described includes the investigation of the mechanical properties of metals and alloys, fracture, corrosion of metals, the defect and catalytic properties of oxides, and the structure of polymers and liquids. Emphasis is placed on the role of light interstitial alloying agents in affecting mechanical properties of metals with particular attention to hydrogen as an embrittlement agent. The Solid State Physics research includes the investigation of electronic properties of phosphors, semiconductors, dichalcogenide layer compounds, hydrocarbon catalysts and magnetic impurities. The study of crystalline defects is a major concern of the program. Dislocation mechanisms of plastic flow have been investigated and point defect studies include diffusion in refractory metals and quantum effects on vacancy migration in helium crystals. Of special interest has been the defect structures conducive to fast ion motion in superionic crystals and the roles of covalent binding and defects in determining the hardness of the transition metal carbide compounds.
