Description

Physieal Metallurgy. In the study of Th alloys, it has been found that the addition of Nb and V to Th produces a slight strengthening effect with the first small additions, but that large additions result in a lowering of strength with corresponding increases in ductility. The melting point of iodide Th was measured as being 1755 deg C. Studies of a series of Th--C alloys, with C content up to 0.13%, indicate that C does not affect the temperatures for the start and completion of recrystallization. ANP Program. Welding specifications were prepared for the joining of Inconel pipe dan … continued below

Physieal Metallurgy.

The melting point of iodide Th was measured as being 1755 deg C. Studies of a series of Th--C alloys, with C content up to 0.13%, indicate that C does not affect the temperatures for the start and completion of recrystallization. ANP Program. Welding specifications were prepared for the joining of Inconel pipe dan fitting. for use with highly corrosive media. The production of spherical particles of alloys of U with Ni, V, Nb, and Mo is being studied. The effect of small differences in test temperature in the stress-rupture life and creep rate of Inconel was studied. The effect of different cleaning procedures on the corrosive action of the fluorides on Inconel is being studied. Additional static and dynamic tests were run in an attempt to find inhibitors for the mass transfer and corrosion exhibited in the metal-hydroxide systems. The study of the compounds formed by the interaction of Ni in the hydroxides has shown the appearance of two new compounds: NaNiO/sub 2/ and LiNiO/sub 2/. Ceramics Research. A ceramic coating was successfully applied to Ni, and a Ni radiator assembly is being coated for the ANP Project. A technique for the synthesis of hafnium carbide was developed. Fabrication Research. Production of enriched U fuel and control red elements for operation of the MTR is described. (W.L.H.)
