Book excerpt: NSA is a comprehensive collection of international nuclear science and technology literature for the period 1948 through 1976, pre-dating the prestigious INIS database, which began in 1970. NSA existed as a printed product (Volumes 1-33) initially, created by DOE's predecessor, the U.S. Atomic Energy Commission (AEC). NSA includes citations to scientific and technical reports from the AEC, the U.S. Energy Research and Development Administration and its contractors, plus other agencies and international organizations, universities, and industrial and research organizations. References to books, conference proceedings, papers, patents, dissertations, engineering drawings, and journal articles from worldwide sources are also included. Abstracts and full text are provided if available.

Download or read book Radiation Damage and Thermal Annealing of Defects in Molybdenum and Tungsten written by A. N. Ivanov and published by . This book was released on 1971 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiation damage to high temperature metal homologues of molybdenum and tungsten as a function of dose and the reactor irradiation temperature is investigated. The studies were conducted with polycrystalline specimens 99.9 percent pure in the case of molybdenum and 99.85 percent in the case of tungsten. Variation if the specific electric resistance was used as a measure of the radiation damage. The saturation effect of the radiation damage and the differences observed between the behavior of molybdenum and tungsten are discussed from the standpoint of the thermal stability of the radiation defects formed in them. The part played by radiation alloying when tungsten is irradiated with large thermal neutron doses is also discussed. A study is made of the thermal annealing of radiation defects in molybdenum and tungsten subjected to various irradiation doses at temperatures above room temperature. The similarity between the three recovery stages in the increase in specific electric resistance, observed during annealing in these metals, and the nature of the defects responsible for the recovery stages are discussed. The variation in fine crystal structure for molybdenum and tungsten during reactor irradiation and subsequent annealing is investigated. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: We have derived the primary recoil spectra for thermal neutron capture in copper and molybdenum, and have calculated the damage energy cross-sections needed to determine the defect production efficiencies from measured resistivity damage rates. These efficiencies, which are in excellent agreement with fully dynamic computer simulations of collision cascades, are compared to the predictions of displacement functions which are currently in use.

Download or read book Radiation Hardening in Neutron Irradiated Molybdenum and Its Alloys written by K. Fukaya and published by . This book was released on 1981 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molybdenum and its alloys [molybdenum-titanium-zirconium (TZM) and Mo-0.56Nb] were neutron-irradiated in the Japan Research Reactor-2 and the Japan Material Testing Reactor at temperature between 873 and 1263 K to fluences in the range 1.2 to 3.0 x 1024 neutrons/m2 (E > 1 MeV). The effect of these irradiations on mechanical properties was investigated and interpreted in terms of change in microstructure. Radiation hardening caused by voids was observed. The formation of precipitates in the irradiated specimen during the neutron irradiation or during the tension test above 800 K contributed additional hardening. The ductile-to-brittle transition temperature (DBTT) of the irradiated molybdenum and TZM was above room temperature, but below 773 K. The total elongation above 773 K suggested the irradiation temperature dependence of DBTT in the irradiated molybdenum. The DBTT of Mo-0.56Nb alloy was only slightly above room temperature. Annealing this alloy at 1273 K resulted in room temperature ductility to near the preirradiation value. These results suggest that the Mo-0.56Nb alloy is a good candidate material for use as a heat protection wall of a fusion reactor.

Download or read book The Nature and Annealing Behavior of Irradiation Damage in Molybdenum written by B. L. Eyre and published by . This book was released on 1965 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Structural defects are observed using transmission electron microscope techniques in molybdenum after neutron or fission fragment irradiation at about 60 C. There is no detectable change in the observable damage on annealing for 1 hr at temperatures up to 600 C, but at 650 C the defects increase in size and become resolvable as dislocation loops. These loops originate from interstitial atoms and the loop size increases with annealing in the range 650 to 950 C. After annealing at 1200 C a well-developed dislocation network is observed and only a few loops remain. No correlation between recovery of microhardness and the observable damage was apparent. Possible reasons are given for the absence of aggregates of vacant lattice sites.
