Available in PDF, EPUB and Kindle. Book excerpt: The study was carried out to determine the critical threshold intensity for stress corrosion cracking of several uranium alloys which are candidates for ballistic penetrator and nuclear shell applications. The data reported here are for alloys in the as-extruded condition only and will serve as base-line data for future studies involving the solution-treated-and-aged alloys.

Book excerpt: The stress corrosion cracking behavior of U-21/4, 41/2, 6 and 8 wt % Nb alloys was evaluated in laboratory air and in aqueous Cl− solutions. Thresholds for crack propagation were obtained in these environments. The data showed that Cl− solutions are more deleterious than air environments. Tests were also conducted in pure gases to identify the species in the air responsible for cracking. These data showed the primary stress corrodent is water vapor for the most reactive alloy, U-21/4% Nb, while O2 is primarily responsible for cracking in the more corrosion resistant alloys, U-6 and 8% Nb. The 41/2% alloy was found to be susceptible in both H2O and O2 environments.

Download or read book A Comparison of the Corrosion and Stress Corrosion Resistance of Two Depleted Uranium Alloys; DU-0.75 Ti and DU-2 Mo written by Patricia P. Trzaskoma and published by . This book was released on 1981 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Considerable experimental work concerning the corrosion rates, stress corrosion behavior, and effects of corrosion on the mechanical properties of depleted uranium alloys has been performed. In this study data for two alloys, DU-0.75 Ti and DU-2 Mo, in three environments have been collected and compared in order to determine whether there are significant differences in their corrosion characteristics and whether these differences warrant a choice of alloy for kinetic energy penetrator applications. In moist air the corrosion rates of the two alloys are low and appear to be of little consequence with respect to this application. In salt fog the corrosion rate of DU-3/4 Ti increases sharply. The weight loss in thirty days is about 7% of the total weight. No data was found for the molybdenum alloy in salt fog. Further experimental work is suggested.

Book excerpt: An investigation was conducted to determine the cause of cracking, during tension, on the surface of tensile specimens of U--Mo alloys. The cracking was observed in alloys that were water quenched from a temperature range in which the body-centered cubic gamma phase was stable and, subsequently, stressed in tension. The investigation was carried out on alloys of U--Mo containing 5 and 4 wt% Mo. It was discovered early in the study that the cracking could be eliminated by testing tensile specimens in a He atmosphere. Because of this result, tensile tests were performed in vacuum O22, impure N2, and purified N2. Additional experiments were done to establish the relation of stress state, temperature, strain rate, O2 pressure, stress magnitude, and grain size to the cracking phenomenon. U--4 wt% Mo and U--5 wt% Mo were compared with respect to microstructure and crystal structure, since both alloys cracked during the tensile test. The origin and propagation of cracks in the microstructure were studied, using motion pictures and metallography. The results of the various experiments showed that the cracking occurred only in tension and was caused by stress-corrosion cracking due to the presence of O/sub 2/ in the atmosphere. The rate of cracking increased as the temperature was increased above 25 deg C. Below 10 deg C cracking was not observed in the U-5 wt% Mo alloy. Cracking was not associated with just one metastable phase. since it was observed in both the U-5 wt% Mo and U-4 wt% Mo alloys, which have different crystal structures when rendered metastable by water quenching from the gamma phase field. The path of fracture was transgranular and was not associated with deformation markings in the grains. (auth).

Available in PDF, EPUB and Kindle. Book excerpt: The stress-corrosion cracking (SCC) behavior of U--6 wt percent Nb in three different heat-treated conditions was investigated. The three heat treatments were: (a) solution quenched (the nonaged condition); (b) solution quenched and aged 6 hours at 250°C (the underaged condition); and (c) solution quenched and aged 80 minutes at 600°C (the overaged condition). The SCC tests utilized smooth, dead-weight loaded, static tensile specimens exposed to nitrogen-saturated or oxygen-saturated water containing 50 ppM chloride ions. The alloy in the solution-quenched condition was not susceptible to SCC when loaded to 90 percent of yield strength in either the oxygen or nitrogen-saturated chloride solutions. The underaged material (6 hours at 250°C) was susceptible to SCC in oxygen or nitrogen-saturated water containing 50 ppM chloride ions. The underaged material was more susceptible to cracking in the oxygen-saturated solution than in the nitrogen-saturated solutions. The SCC in the underaged material proceeded by a principally intercrystalline fracture mode with the overload condition being principally transgranular. The overaged material also exhibited SCC, but to a lesser extent than the underaged material. Here again, cracking was more pronounced in the oxygen-saturated solution than in the nitrogen-saturated solution. The overaged material fractured by a combined SCC mode and mechanical-cracking mode, i.e., stress-corrosion cracks were growing at the same time corrosion was reducing the cross-sectional area of the specimen. The importance of knowing alloy characteristics relates to considerations of design, environmental behavior, and economics.

Available in PDF, EPUB and Kindle. Book excerpt: The ability to monitor corrosion and stress-corrosion cracking of uranium 4.5-weight percent niobium was investigated. The acoustic emissions from stress-corrosion cracking were monitored using smooth four-point bend specimens, which were immersed in oxygen-saturated water containing chloride ions. The acoustic emissions from corrosion were monitored from rectangular corrosion coupons. These latter specimens were exposed to nitrogen-saturated and oxygen- saturated solutions of distilled water and distilled water with chloride ions. Dilute solutions of hydrochloric acid were also used. Findings show that stress- corrosion crack monitoring of the alloy was successful. Corrosion monitoring of the alloy showed a direct correlation between corrosion rate (based on weight loss) and total acoustic emissions. For a specific range, one can calculate the corrosion rate of uranium alloys in a corrosive solution from the total acoustic emissions generated. Studies to determine the source of corrosion-induced acoustic emissions were inconclusive.
