More extensive use of aluminum alloys for service at cryogenic temperatures has resulted in a need for more detailed information about their behavior in both the plain and welded conditions at these temperatures. For example, the moduli, fatigue strengths and those properties related to toughness, such as notch sensitivity and tear resistance, are of prime importance. These properties have been studied at the Alcoa Research Laboratories and a brief review of some of the more important findings follows. [Pg.637]

The higher inherent corrosion resistance of aluminum alloys in saltwater, as compared to steel, has led to the use of a wet/dry saltwater immersion-type test being used at the Alcoa Laboratories instead of the ASTM B 117 procedure. In fact, the continuous immersion of aluminum bonded joints in 3.5% sodium chloride solution or even natural seawater may not deteriorate such joints as much as distilled or deionized water exposure. The amount of... [Pg.274]

Figure 8.1 Effect of pH on corrosion of 1100-H14 alloy (aluminum) by various chemical solutions. Observe the minimal corrosion in the pH range of 4-9. The low corrosion rates in acetic acid, nitric acid, and ammonium hydroxide demonstrate that the nature of the individual ions in solution is more important than the degree of acidity or alkalinity.

J. Dean Minford obtained his Ph.D. degree in bio-organic chemistry from the University of Pittsburgh in 1951. In 1953, he joined the Alloy Technology Division of Alcoa Laboratories and in 1976 was made Scientific Associate of Alcoa. Dr. Minford has published over 40 papers and has been a consultant since he retired from Alcoa. He was a member of ASTM Conunittee D14 on Adhesives and D24 on Sealants. Dr. Minford is the foremost authority in joining aluminum with adhesives. [Pg.452]

Plots of maximum depth of pitting corrosion on 1000 and 3003 alloy sheet and the percent loss in strength resulting from exposure to seacoast atmosphere at Point Judith, Rhode Island. Both curves show the self-stopping nature of pitting corrosion of aluminum but at different rates of change. The rationale behind the difference is discussed in Section 19.7.

Plot of corrosion potentials of pure aluminum and binary aluminum plus copper alloys, plus the two stoichiometric precipitates. The binary alloys were fully solution heat treated and quenched as rapidly as possible to retain the maximum amount of copper in solid solution. Note that the addition of copper raises the corrosion potential of pure aluminum by about 0.14 V. (Courtesy of Alcoa Technical Center, Marsha Egbert.)... [Pg.507]
