This book was released on 1967 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear research and power reactors are now being designed which must operate at temperatures and coolant environments dictating the use of nickel-base and refractory metal alloys for structural components, fuel cladding, and power equipment. Investigation of the effects of irradiation and environment upon the mechanical properties of several nickel-base and refractory metal alloys has been initiated at the Pacific Northwest Laboratory. Tension specimens of Inconel 600, Inconel 625, Inconel 702, Inconel 718, Incoloy 800, Hastelloy C, Hastelloy N, Hastelloy X-280, and Hastelloy R-235 have been irradiated to exposures exceeding 1 x 1021 nvt (E > 1 Mev) in 50 C water, 280 C water, and 740 C gaseous environments. These specimens have been tested in the pre- and postirradiated conditions at room temperature, 300 C, and 650 C. Several metallurgical conditions of the materials have also been examined and the changes in mechanical properties due to the irradiation have been noted. The Cb-1 Zr, Cb-752, TZM Mo, and W-25 Re refractory metals have been irradiated at ambient temperatures, and the effects of irradiation upon the mechanical properties have been evaluated at room temperature and 1090 C. The data obtained for both the nickel-base and refractory metal alloys tested indicate that there is a marked effect upon the mechanical properties due to the thermal environment. In addition to this effect, effects due to the irradiation were also found. Comparison of the elevated temperature data to the room temperature data shows a marked decrease in both strength and ductility. Metallographic examination of these materials is continuing in an attempt to find the cause of these damages.

Download or read book Effects of Neutron Irradiation on the Microstructure of Niobium and Niobium Base Alloys written by DJ. Michel and published by . This book was released on 1979 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The microstructure and microhardness of niobium and commercial prototype niobium-base alloys have been investigated following fast neutron irradiation to a fluence of 1.1 x 1022 neutrons (n)/cm2 (0.1 MeV), 4 displacements per atom (dpa), at 482°C. The purpose of this work was to determine the effects of molybdenum and zirconium alloy additions on the resistance of niobium-base alloys to neutron irradiation. Neutron irradiation of the niobium and Nb-1Mo alloy produced very small voids whose mean diameters were in the range of 30 to 35 Å. In all other alloys, however, no voids were observed and the principal effect of the neutron irradiation was to form a high density of 30 to 40 Å diameter dislocation loops which are believed to be primarily of interstitial character. The effect of fast neutron irradiation was to increase the microhardness of both niobium and all its alloys, with the largest increase in the Nb-1Zr alloy and the smallest increase in the ternary Nb-5Mo-1Zr alloy. Previous work on niobium and Nb-1Zr alloy has shown that a vacancy trapping mechanism is particularly effective at irradiation temperatures up to 600°C for fast neutron fluences of 2.5 x 1022 n/cm2 (0.1 MeV). The observation from the present experiments that molybdenum and zirconium additions were effective in the suppression of void formation suggests that a vacancy trapping mechanism was operative in the present alloys. The smaller hardness increase observed for the ternary alloys suggests that these alloys may maintain good engineering properties in addition to their improved resistance to void formation.
Download or read book Effects of Neutron Irradiation on Precipitation Hardening Alloys written by C. R. Cupp and published by . This book was released on 1963 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of neutron irradiation on age-hardening alloys are of great importance in determining the usefulness of these alloys in reactors and are, in addition, of fundamental interest in determining the basic mechanisms of radiation effects. Most of the work has been on alloys irradiated as supersaturated solid solutions, although some data are available for specimens irradiated in the aged condition. Irradiation can enhance solid state diffusion sufficiently to initiate precipitation or to allow growth of existing precipitates, which can lead to overaging. In addition, precipitate nuclei can be redissolved by neutron irradiation. Either overaging or re-solution will reduce the strength of the alloy and will affect physical properties as well.

Available in PDF, EPUB and Kindle. Book excerpt: High-performance alloys that can withstand operation in hazardous nuclear environments are critical to presentday in-service reactor support and maintenance and are foundational for reactor concepts of the future. With commercial nuclear energy vendors and operators facing the retirement of staff during the coming decades, much of the scholarly knowledge of nuclear materials pursuant to appropriate, impactful, and safe usage is at risk. Led by the multi-award winning editorial team of G. Robert Odette (UCSB) and Steven J. Zinkle (UTK/ORNL) and with contributions from leaders of each alloy discipline, Structural Alloys for Nuclear Energy Applications aids the next generation of researchers and industry staff developing and maintaining steels, nickel-base alloys, zirconium alloys, and other structural alloys in nuclear energy applications. This authoritative reference is a critical acquisition for institutions and individuals seeking state-of-the-art knowledge aided by the editors’ unique personal insight from decades of frontline research, engineering and management. Focuses on in-service irradiation, thermal, mechanical, and chemical performance capabilities. Covers the use of steels and other structural alloys in current fission technology, leading edge Generation-IV fission reactors, and future fusion power reactors. Provides a critical and comprehensive review of the state-of-the-art experimental knowledge base of reactor materials, for applications ranging from engineering safety and lifetime assessments to supporting the development of advanced computational models.

Available in PDF, EPUB and Kindle. Book excerpt: Studies to determine the effect of neutron environment on the stress-rupture properties of A-286, Hastelloy X, and René 41 alloys are described. Specimens were irradiated in the Engineering Test Reactor at approximately 540 and 650 C to fast neutron dosages of 4 to 11 x 1019 nvt (En ? 1 Mev). Postirradiation stress-rupture tests were conducted at 540 and 650 C. The effect of reheat treatment following irradiation was investigated.
