Effects of Fast-Neutron Irradiation on Tensile Properties and Swelling Behavior of Vanadium Alloys

Pages : 16
Book Description
Fast-neutron-induced void formation in commercial pure vanadium is dramatically reduced by additions of titanium and/or chromium. As little as 1 percent by weight titanium decreases the void number density and void volume fraction by factors of 30 and 100, respectively, compared with pure vanadium after exposure at 525 C (977 F) to a fluence of 1.1 x 1022 n/cm2, En > 0.1 MeV. Additions of 3 percent by weight titanium or greater suppress void formation entirely under the same exposure conditions. Alloys of 10 and 15 percent by weight chromium have also been found beneficial in limiting swelling. Internal-friction measurements show that the reduction in void formation in the vanadium-titanium alloys may be partly related to the removal of interstitial impurities, oxygen, and nitrogen by the titanium to form a coherent precipitate of Ti3O2 or a complex oxynitride. Excess oxygen in the alloy after consumption of the available titanium as a precipitate results in increased void formation and also loss of precipitate coherency.
Extractive Metallurgy of Niobium
Author: A.K. SuriPublisher: Routledge
ISBN: 1351448978
Category : Science
Languages : en
Pages : 272
Book Description
The growth and development witnessed today in modern science, engineering, and technology owes a heavy debt to the rare, refractory, and reactive metals group, of which niobium is a member. Extractive Metallurgy of Niobium presents a vivid account of the metal through its comprehensive discussions of properties and applications, resources and resource processing, chemical processing and compound preparation, metal extraction, and refining and consolidation. Typical flow sheets adopted in some leading niobium-producing countries for the beneficiation of various niobium sources are presented, and various chemical processes for producing pure forms of niobium intermediates such as chloride, fluoride, and oxide are discussed. The book also explains how to liberate the metal from its intermediates and describes the physico-chemical principles involved. It is an excellent reference for chemical metallurgists, hydrometallurgists, extraction and process metallurgists, and minerals processors. It is also valuable to a wide variety of scientists, engineers, technologists, and students interested in the topic.
