Tensile, Fatigue, and Creep Properties of Forged Aluminum Alloys at Temperatures Up to 800 deg. F

This paper presents data on the tensile strength, fatigue strength, creep properties, and thermal expansion of forged aluminum alloys XBl8S, 185, 24S, and 325, which are pertinent to the application of these alloys in the temperature range from 700 to 8Q%O F. Included arc data taken from published sources, unpublished material made available through the courtesy of the Aluminum Company of America and the National Bureau of Standards, and original data, obtained at Battelle Memorial Institute, which extend this previous information. The work also contains a critical discussion of the data and their application to design of aircraft engine.
