Book Description
At the present time, 28 aluminum and 728 are used in applications in which river water attains temperatures as high as about 180 deg F. The 2S is aluminum of commercial purity, and the 72S is a high-purity aluminum-base alloy containing 1 per cent zinc. Both of these materials are relatively weak at room temperature as well as at elevated temperatures. The objective of the present work was the development of aluminum-base alloys which had higher load-carrying capacities at all temperatures up to 600 deg F. without an appreciable sacrifice in resistance to corrosion by water at elevated temperatures and also without an appreciable increase in thermal neutron cross-section value. Accordingly, the work was divided into two phases. The first dealt with the development of alloys having better load-carrying capacity, and the second was concerned with the effects of temperature on the corrosion resistance of the experimental and some commercial alloys in water. The first phase is described in Section I of the report, and the second in Section II of the report.
