Book Description
This four-volume reference work builds upon the success of past editions of Elsevier’s Corrosion title (by Shreir, Jarman, and Burstein), covering the range of innovations and applications that have emerged in the years since its publication. Developed in partnership with experts from the Corrosion and Protection Centre at the University of Manchester, Shreir’s Corrosion meets the research and productivity needs of engineers, consultants, and researchers alike. Incorporates coverage of all aspects of the corrosion phenomenon, from the science behind corrosion of metallic and non-metallic materials in liquids and gases to the management of corrosion in specific industries and applications Features cutting-edge topics such as medical applications, metal matrix composites, and corrosion modeling Covers the benefits and limitations of techniques from scanning probes to electrochemical noise and impedance spectroscopy
Hydrogen Decreased Ductility of a U-6%NB Alloy

Book Description
Hydrogen decreases the ductility of uranium alloys without resulting in a brittle failure. Due to the low solubility of hydrogen and the propensity to form hydrides in uranium and its alloys, it might be expected that the mechanism of embrittlement would be the stress-induced hydride formation and cleavage mechanism. However at 2-5 wppm levels, hydrogen significantly decreases the ductility of the alloy without resulting in a cleavage-based mechanism. We have chosen the uranium-niobium (6wt.%) alloy system to investigate the hydrogen embrittlement phenomena in uranium-based alloys. The alloy was gas - phase charged at 800 C at pressures ranging from 10−4 to 10−1 MPa using ultra-high purity hydrogen gas (99.999%) followed by water quenching. Hydrogen contents ranged from 0 wppm (vacuum outgassed) to 20 wppm. Tensile tests were performed at strain rates of 10−3 and 10−5 sec−1. The elongation and reduction in area decrease rapidly from 0 wppm to 5 wppm with little further reduction at 20 wppm. Hydrogen has no effect on the yield strength, ultimate tensile strength and work hardening coefficient. Scanning electron microscopy of the fracture surfaces shows that all of the samples fail by ductile microvoid coalescence. Concomitant with the reduction in ductility due to increased hydrogen content, the micro void size also decreases with increasing hydrogen content. This alloy has numerous inclusions and the microvoids all nucleate at the inclusions. At low hydrogen contents, the microvoids appear to nucleate only on the largest inclusions (H"0 [mu]m). As the hydrogen content increases, the microvoids tend to also nucleate on smaller inclusions (
