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).
Book Synopsis Research on the Basic Nature of Stress Corrosion for Various Structural Alloys at Room and Elevated Temperatures by : Frank A. Crossley

This book was released on 1964 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wrought, high-strength aluminum alloys characteristically have markedly inferior resistance to stress corrosion in the short-transverse direction relative to resistance in the longitudinal and long-transverse directions. The anisotropy of resistance has been shown to be due to marked anisotropy of microstructure. Investigation of experimental and commercial 1 in. plate showed that the elongated, plate-like grain structure usually found in commercial materials was associated with short life while equiaxed or irregular grain structure was associated with significantly longer life. Excess alloy content resulting in second-phase particles in the microstructure contributes to the development of the undesirable elongated grain structure. Exposure at 650F under stress for times of 1400 or 2000 hr gave no indication that the steels PH 13-8 Mo and PH 14-8 Mo are susceptible to hot salt stress corrosion. Experiments to determine the kinetics of hot salt stress-corrosion cracking of Ti-8Al-1Mo-1V alloys are described. Cracking was observed at 500F, 50F lower than the lower temperature limit reported in prior investigations.

Book Synopsis Research on the Basic Nature of Stress Corrosion for Various Structural Alloys at Room and Elevated Temperatures by : Frank A. Crossley
Download or read book Research on the Basic Nature of Stress Corrosion for Various Structural Alloys at Room and Elevated Temperatures written by Frank A. Crossley and published by . This book was released on 1963 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Program objectives were: (1) to study the effect of microstructure on susceptibility to stress corrosion cracking in the short-transverse direction of 7075-T6 aluminum alloy; and (2) to study the kinetics of stress-corrosion cracking at elevated temperature of candidate materials for structural applications in the trisonic transport in the presence of sea salt. It was hypothesized that the poor resistance to stress corrosion of high-strength, wrought aluminum alloys was due to the layered-type microstructure characteristic of these materials. Short life was associated with the layered-type of grain structure characteristic of commercial material, and long life was associated with irregular or equiaxed grain structures. The experimental results gave good support to the hypothesis.

Book Synopsis Stress-corrosion Cracking of Aluminum Alloys by : F. H. Haynie
Download or read book Stress-corrosion Cracking of Aluminum Alloys written by F. H. Haynie and published by . This book was released on 1966 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report deals with the stress-corrosion cracking of aluminum alloys, and it represents an effort by DMIC to expand on the information contained in DMIC Memorandum 202, 'Stress-Corrosion Cracking of Aluminum Alloys', dated February 15, 1965. DMIC Report 228 begins by presenting a comprehensive definition of stress-corrosion cracking. This is followed by sections dealing with (1) the historical development and growth in awareness of the problem, (2) the mechanisms involved, and (3) the theory of stress-corrosion cracking. A section on experimental techniques is presented. These techniques include test methods used to determine the susceptibility of alloys to stress-corrosion cracking, as well as more refined methods of studying the fundamental mechanisms of the problem. Different evaluation methods, applicable to obtaining the different objectives of stress-corrosion testing, are also presented. All of the foregoing serve as background to the sections on stress-corrosion-cracking behavior of aluminum alloys and preventive measures. (Author).
Book Synopsis Environmental Corrosion-fatigue Behavior of Aluminum Alloys by : D. N. Williams
Download or read book Environmental Corrosion-fatigue Behavior of Aluminum Alloys written by D. N. Williams and published by . This book was released on 1970 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of environment on fatigue behavior are quite intimately related to such test variables as stress intensity, cyclic frequency, and temperature. The effect of these variables has been shown to be quite complex. However, a consistent pattern of behavior is beginning to emerge which, it is hoped, will lead to a considerably changed understanding of the corrosion-fatigue process. It is considered probable that an increased understanding of the corrosion-fatigue process will also contribute measureably to an improved understanding of general fatigue processes. Material variables such as composition, directionality of properties, and microstructure, have important effects on corrosion-fatigue behavior of aluminum alloys. However, it appears that these variables, at least in gaseous environments, may be important largely because of their effects on the mechanical behavior of aluminum alloys. On the other hand, studies in seawater suggest that these variables become increasingly important as the corrosive nature of the environment increases. This memorandum discusses in detail the effects of both test variables and material variables on corrosion fatigue. In addition, current theories of corrosion-fatigue mechanisms are outlined, and several methods of preventing corrosion fatigue are suggested. (Author).
