FUNDAMENTALS OF DIFFUSIONAL BONDING--IV. Fourth Annual Progress Report for July 1, 1958 through June 30, 1959

PDF Version Also Available for Download.

Description

Investigatlon of interdiffusion in the aluminumuranium system and of the effects of applied pressure on such systems was about completed. The growth kinetics of the UAl/sub 3/ phase were determined at 400 to 600 C and at pressures of 1 1/4, 5, and 10 tsi. The origin of the macroscopic defects occurring in the UAl/sub 3/ layer during interdiffusion was clarified. The solubility range of UAl/sub 3/ was determined by a nuclear track emulsion technique to be about 2.6 at.% uranium. Exploratory runs were made with incremental diffusion couples of aluminum vs. UAl/sub 3/ and of UAl/sub 3/ vs. uranium ... continued below

The solubility range of UAl/sub 3/ was determined by a nuclear track emulsion technique to be about 2.6 at.% uranium. Exploratory runs were made with incremental diffusion couples of aluminum vs. UAl/sub 3/ and of UAl/sub 3/ vs. uranium disks to determine the growth rates of the UAl/sub 4/ and UAl/sub 2/ phases. A theoretical estimate was made of the importance of pressure-induced shifts in equilibrium concentrations in intermetallic layer growth in the aluminum-uranium and aluminum-nickel systems.
