Book Description
Many ductile metals in intimate contact with thin coatings of low melting solid metal which exhibit liquid metal embrittlement, also manifest severe embrittlement when tested at temperatures below the melting point of the coating. A significant decrease in stress, strain, and reduction-in-area occurs at fracture. Fracture propagates fast, but at a rate which is one or two orders of magnitude slower than that in liquid metal environments. Fracture occurs by brittle intergranular or transcrystalline mode with multiple cracks and branching. This new phenomena is known as solid metal induced embrittlement of metals (SMIE). SMIE also occurs when the embrittling metal is present as an internal environment in the base metal such as inclusions. This report describes the occurrence of SMIE in metals and alloys used in industry and presents results of recent investigations. It describes the effects of time, temperature, and stress on SMIE. It discusses the occurrence, the mechanisms of SMIE, and its similarity to LME. This new phenomena must be considered while investigating environmentally induced failure of failure analysis of metals and alloys.
Corrosion by Liquid Metals

Book Description
The Corrosion Resistant Metals Committee and the Nuclear Metallurgy Committee of the Institute of Metals Division of The Metallurgical Society of AlME sponsored a 2-1/2 day symposium on "Corrosion by Liquid Metals". The symposium was held in Philadelphia, October 13-15, 1969, during the 1969 Fall Meeting of the Metallurgical Society and the Materials Engineering Con gress of the American Society for Metals. Cosponsors included the American Society for Metals and the American Nuclear Society. The purpose of the symposium was to bring together the several aspects of the subject of corrosion by liquid metals, so that perspective could be provided on the entire subject, to help in dividuals dealing with liquid metal corrosion problems acquire a sound basis of understanding, and to provide an opportunity for discussion between those doing research in this field. An exposition of the subject is timely, in view of the in creasing development of liquid metal heat and power sources for special purposes, including heat-pipe systems, NASA's SNAP power systems, and the AEC's liquid metal fast breeder reactor system. This book contains the proceedings of the symposium divided into four separate topics: I. Corrosion of Steels by Sodium, II. Alkali-Refractory Metal Interactions, III. Corrosion by Non-Alkali Metals, and IV. Analysis of Solid-Liquid Metal Inter actions (two sessions).
Liquid and Solid Metal Embrittlement

Book Description
The recent literature on embrittlement induced by solid or liquid metal environments is critically reviewed. Evidence in support of an enhanced shear model of embrittlement is provided for amorphous metals, while decohesion is shown to be a viable concept for crystalline metals. The usefulness of the concept of specificity of embrittlement is questioned on the basis of evidence for new embrittlement couples as the range of experimental conditions is varied. In particular, strain rate and temperture are shown to have extremely important effects on the degree of embrittlement. (Author).
Atomistics of Fracture

Book Description
It is now more than 100 years since certain detrimental effects on the ductility of iron were first associated with the presence of hydrogen. Not only is hydrogen embrittlement still a major industri al problem, but it is safe to say that in a mechanistic sense we still do not know what hydrogen (but not nitrogen or oxygen, for example) does on an atomic scale to induce this degradation. The same applies to other examples of environmentally-induced fracture: what is it about the ubiquitous chloride ion that induces premature catastrophic fracture (stress corrosion cracking) of ordinarily ductile austenitic stainless steels? Why, moreover, are halide ions troublesome but the nitrate or sulfate anions not deleterious to such stainless steels? Likewise, why are some solid metals embrit tled catastrophically by same liquid metals (liquid metal embrit tlement) - copper and aluminum, for example, are embrittled by liquid mercury. In short, despite all that we may know about the materials science and mechanics of fracture on a macroscopic scale, we know little about the atomistics of fracture in the absence of environmental interactions and even less when embrittlement phe nomena such as those described above are involved. On the other hand, it is interesting to note that physical chemists and surface chemists also have interests in the same kinds of interactions that occur on an atomic scale when metals such as nickel or platinum are used, for example, as catalysts for chemical reactions.

Book Description
A research project concerned with liquid-metal embrittlement (LME) is summarized. Of particular interest have been quantitative determinations of the fracture behavior of simple embrittlement couples such as pure solid zinc in pure liquid mercury, in order to provide the basis for a better understanding of the mechanism of LME.
