Available in PDF, EPUB and Kindle. Book excerpt: Experiments have been carried out on high-velocity deformation and fracture of metals. Aluminum and copper single crystals and polycrystalline specimens have been subjected to explosive loading and the following results havebeen obtained: (1) Crystal orientation influences the reaction of the metal specimens at pressures of testing above 100 kilobars. The orientation factor causes a redistribution of flow in the reflected tensile wave. (2) The fracture of the specimen is not instantaneous, but times between 104 and 106 sec are required. (3) A measure of the macroscopic theoretical strength of the metal has been obtained. (4) Crack velocities have been calculated. (5) The concept of an energy criterion for fracture, rather than a maximum stress criterion, is implied from the data.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Embrittlement of Zinc Monocrystals and Bicrystals by Mercury and Gallium written by M. H. Kamdar and published by . This book was released on 1965 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was made of the fracture behavior of zinc monocrystals and asymmetric bicrystals tested in tension at room temperature while coated with liquid mercury or gallium. The results are consistent with the view that adsorption of the active liquid metal specifically at some stable obstacle to slip is a prerequisite for embrittlement. Thus, carefully prepared and handled monocrystals, oriented for single slip and tested in tension, are not embrittled by mercury or gallium unless these liquid metals are adsorbed specifically at kink bands formed during deformation in the vicinity of the grips. The data from the bicrystal studies provide experimental support for the theoretical criteria for fracture in zinc proposed by Likhtman-Shchukin and Gilman. From this data, a value of 48 = 3 ergs/sq cm was deduced for the fracture surface energy of zinc in the presence of mercury, in good agreement with an earlier determination of this quantity by the present authors. The results of the investigation are discussed with regard to earlier work by Shchukin and others. (Author).

Kirchner and published by . This book was released on 1980 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The following topics are covered in this report: (1) Localized impact damage in zinc sulfide, and (2) Crack growth from small flaws in larger grains in alumina. Zinc sulfide specimens were damaged by static and impact loading using glass spheres. The various types of cracks were identified and their sizes were measured. The maximum impact loads were estimated by several methods including an experimental method based on the assumption that static and impact loads are equal at equal indentation radii, a semi-empirical method previously developed on this program and a method suggested by Hutchings. Crack growth in alumina was simulated for the case of small flaws in larger surface crystals to determine the range of crystal sizes and loading rates in which single crystal fracture energies would be expected to control fracture. This should be expected only for large crystals and very high loading rates.
