This book was released on 1977 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metallographic and fractographic studies of fracture in single crystals of aluminum and zinc, and in polycrystalline aluminum, cadmium and tin in liquid-metal environments and in air are described. The commonly suggested mechanism for liquid-metal embrittlement--that chemisorption of liquid-metal atoms facilitates tensile rupture of stressed interatomic bonds at crack tips--is not supported by the present observations. Rather, observations of extensive slip around crack tips and dimpled fracture surfaces suggest that crack growth in embrittling liquid-metal environments occurs by plastic flow, but with considerably less blunting occurring at crack tips than in air. It is proposed that liquid-metal embrittlement can be explained on the basis that chemisorption of liquid-metal atoms facilitates the nucleation of dislocations at crack tips. Such an effect would produce sub-critical crack growth, change the distribution of slip around cracks and reduce the extent of blunting at crack tips, but would not generally influence bulk flow characteristics. The relevance of these results to hydrogen-embrittlement, stress-corrosion cracking, and ductile versus brittle behaviour in general is discussed. (Author).

Orava and published by . This book was released on 1966 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microstrain and etching experiments were conducted on 70/30 brass single crystals to determine the effect of the presence of liquid mercury at the surface on deformation characteristics in the early stages of plastic flow. It was revealed that dislocations become mobile at stresses as low as 0.04 kg.mm- to the -2 in annealed crystals, a sharp contrast to previous observations. A model is presented to explain the microstrain characteristics. A debris layer near the surface was observed to a depth of about 20 microns after 2 x 10 to the -3 plastic shear strain, irrespective of the presence of mercury. Thus, liquid mercury is equally as effective as an oxide film in impeding the emergence of dislocations from a crystal. Since the degree to which this type of behavior inhibits crack relaxation could not be determined, it was not possible to rigorously establish this as the mechanism for liquid metal embrittlement.

Available in PDF, EPUB and Kindle. Book excerpt: The role of plastic deformation in the initiation and propagation of cracks in Cu-17A1 alloy embrittled by liquid mercury has been studied. It is proposed that extensive plastic deformation and work hardening must occur at the crack-tip during propagation in order to raise the local flow stress to a critical level at which the maximum normal stress is equal to the cohesive strength. Strong indication is given that a 'critical applied stress' criterion for fracture is not applicable for this material. Micro-cracks are formed at weakened grain boundaries and a period of stable crack growth made over a period of increasing applied stress may be necessary before the crack is long enough to become unstable.
