This book was released on 1970 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was made of the factors affecting the change of pH with time of initially acidic (pH = 0 to 2) 3% NaCl solutions, resulting from the dissolution of turnings of a commercial 7075 alloy, an Al-5.3 wt. pct. Zn-2.5 wt. pct. Mg alloy, and pure aluminum. It was shown that for solutions containing large volume fractions of the solids, a steady pH is attained which is associated with the onset of precipitation of Al(OH)3. It is suggested, by analogy, that the formation of the steady pH region at the tips of stress-corrosion cracks in aluminum alloys is also associated with the onset of precipitation of Al(OH)3, and that the pH in this region can be calculated from the solubility product of freshly precipitated Al(OH)3. The study also suggests that similar conclusions apply to the stress-corrosion cracking of magnesium alloys. (Author).

Download or read book Mechanisms of Stress Corrosion Cracking and Liquid Metal Embrittlement Particularly in High Strength Aluminium Alloys written by S. P. Lynch and published by . This book was released on 1977 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metallographic and fractographic observations of sub-critical crack growth in a precipitation-hardened AlZn-Mg alloy in liquid-metal, aqueous, and water-vapour/air environments suggest that stress-corrosion cracking and liquid-metal embrittlement in this alloy involve a common mechanism. Sub-critical crack growth in all these environments can produce entirely dimpled fracture surfaces and, in liquid-metal and aqueous environments, crack growth can occur extremely rapidly. It is proposed that stress-corrosion cracking and liquid-metal embrittlement in aluminium alloys (and possibly other materials) can be explained on the basis that chemisorption of environmental species facilitates nucleation of dislocations at crack tips. Such a process would produce sub-critical crack growth with less blunting at crack tips than in inert environments and, hence, would explain observations that dimples on fracture surfaces after SCC are smaller and shallower than those on overload fractures. The results suggest that neither dissolution nor hydrogen-embrittlement processes occurred during stress-corrosion cracking in aluminium alloys. (Author).

This book was released on 1965 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mechanism of stress-corrosion cracking in 7079 aluminum alloy was investigated by analysis of microstructural changes that occur during exposure to 3.5 per cent NaCl solution. During the corrosion reaction dislocation networks were generated within the grains and along strain-contour bands. Grain-boundary voids occurred where several of these bands originated or terminated. This suggests that the intragranular structure develops as a result of hydrogen entering the alloy and that the voids are propagated under applied load to form grain-boundary cracks. This study is in the preliminary stages and is being continued. (Author).
