Available in PDF, EPUB and Kindle. Book excerpt: A study has been made of the mechanism of hydrogen embrittlement (HE) in Al-Zn-Mg alloys, and of the role of hydrogen in the intergranular stress-corrosion cracking (I-SCC) of these alloys. Up to 300 ppm (1 at pct) hydrogen was introduced into a high-purity Al-5.6Zn-2.6Mg alloy, either by room temperature polishing with aqueous slurries of alumina particles or by exposure to water-vapor-saturated air (WVSA) at 70 C, and subsequent tensile tests (stress rate approx 0.0001/s) in inert environments caused brittle intergranular fracture. Embrittlement was found to be reversible, the tensile properties being completely restored when the hydrogen was outgassed. At low hydrogen contents, embrittlement was suppressed by the use of high strain rates (approx 0.01/s), but could not be suppressed by impact testing at large hydrogen concentrations. The intergranular fracture surfaces were observed to be associated with a fragmented layer, and electron-diffraction experiments indicated that it corresponded to a hexagonal aluminum hydride, Al H3, with a = 2.90 A and c = 4.55 A. This hydride, considered to be stress-induced, was unstable in laboratory air, slowly decomposing to FCC Al. It is concluded that internal HE in this alloy occurs by repeated cycles of the formation and rupture of this brittle hydride.

Book The Role of Hydrogen in the Stress Corrosion Cracking of High Strength Aluminum Alloys

Download or read book The Role of Hydrogen in the Stress Corrosion Cracking of High Strength Aluminum Alloys written by A. W. Thompson and published by . This book was released on 1981 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this program has been to understand the stress corrosion cracking (SCC) behavior of high-strength aluminum alloys, and in particular to understand the role played by hydrogen embrittlement in such cracking. The approach taken was to study microstructural effects on both hydrogen embrittlement and SCC, and to establish, insofar as possible, microstructural and fractographic correlations with cracking behavior, and detailed understanding of the mechanical behavior of hydrogen-charged material. When this program began, there existed only a single unconfirmed report of hydrogen embrittlement in a high-strength aluminum alloy. That report was confirmed (on 7075-T651), and extensive additional evidence acquired (on 7075, 2124 and 7050, in a variety of heat treatments), permitting us to assemble a complete and detailed description of hydrogen embrittlement and its dependence on microstructure in Al alloys, in some 14 publications. A parallel effort on SCC behavior has also been conducted, using the technique of Mode I - Mode III testing to provide information on the relative contributions of hydrogen embrittlement and anodic dissolution to SCC. The Mode I data for 7075 showed a close parallel to the hydrogen charging results, in microconstructural dependence and in fractography. The Mode III data showed that the anodic dissolution component of SCC is small compared to hydrogen embrittlement, and moreover, has a much weaker dependence on microstructure. (Author).

Book Stress Corrosion Cracking of Wrought and P M High Strength Aluminum Alloys

Download or read book Stress Corrosion Cracking of Wrought and P M High Strength Aluminum Alloys written by A. W. Thompson and published by . This book was released on 1984 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The combined results of the first three years of the program are presented, with emphasis on the stress corrosion cracking and hydrogen embrittlement of the PM 7090 Al alloy. Additional results on 7075 are also given. In particular, the role of temper and loading mode in susceptibility were examined for three test methods---time to failure of notched round bar specimens in a brine solution; straining electrode tests on notched round specimens under cathodic charging; and tensile tests on hydrogen pre-charged notched round specimens. These tests form the basis for an extensive, completed Ph. D. thesis which is summarized here. Stress corrosion testing has also been conducted on 7075 in aluminum chloride solutions and on HP 7075. We remain confident that we have established the basis and a good portion of the results necessary to understand, predict and model the role of hydrogen in stress corrosion cracking of high-strength aluminum alloys.
