Available in PDF, EPUB and Kindle. Book excerpt: Two types of stress corrosion cracking occur in U-6 wt% Nb. Intergranular (anodic dissolution) cracking occurs in aqueous Cl− environments. Transgranular (oxide stress rupture) cracking occurs in gaseous environments containing oxygen. Aging the quenched alloy at 200 deg C for 2 hours doubles the yield strength but only slightly lowers the stress corrosion cracking threshold. (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.

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).

This book was released on 2012-12-06 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: This series was organized to provide a forum for review papers in the area of corrosion. The aim of these reviews is to bring certain areas of corrosion science and technology into a sharp focus. The volumes of this series are published approximately on a yearly basis and each contains three to five reviews. The articles in each volume are selected in such a way as to be of interest both to the corrosion scientists and the corrosion technologists. There is, in fact, a particular aim in juxtaposing these interests because of the importance of mutual interaction and interdisciplinarity so important in corrosion studies. It is hoped that the corrosiori scientists in this way may stay abreast of the activities in corrosion technology and vice versa. In this series the term "corrosion" is used in its very broadest sense. It includes, therefore, not only the degradation of metals in aqueous en vironment but also what is commonly referred to as "high-temperature oxidation. " Further, the plan is to be even more general than these topics; the series will include all solids and all environments. Today, engineering solids include not only metals but glasses, ionic solids, polymeric solids, and composites of these. Environments of interest must be extended to liquid metals, a wide variety of gases, nonaqueous electrolytes, and other non aqueous liquids.
