Hydrogen Diffusion in Metals

ISBN: 9783038350248 出版年：2014 页码：362 Trans Tech Publications Ltd

Due to its small size, the hydrogen atom is, wanted or unwanted, an ubiquitous diffusant in many metallic systems. it has long been known for its harmful effect upon mild steel sheet; the deleterious phenomenon of hydrogen-embrittlement having been recognized since the early days of the industrial revolution. its behavior in some metals is further complicated by its tendency to form hydrides with the metal, or with various non-metallic impurities. the ability of some metals and alloys to store large quantities of hydrogen – first recognized in the 19th century - is another complicating factor. the complexity of metal-hydrogen behavior was undoubtedly also the cause of the mistaken ‘cold fusion’ claims of the late 1980s. the present issue comprises a compilation of hydrogen diffusion and permeation data in metals.
