Development of Cast Aluminum Alloys for Elevated-Temperature Service
Abstract
An experimental investigation was conducted to develop an aluminum alloy for service at elevated temperatures. The development work was divided into three parts to determine: (1) The effects of heat treatment and exposure to elevated temperatures on the tensile properties of the various alloys subsequently cooled to room temperature; (2) the effect of various alloy additions on the room-temperature and elevated-temperature properties of aluminum, 6-percent-magnesium alloys; and (3) the improvement in high-temperature creep properties of some of the optimum compositions. From the results of the investigation an experimental alloy that appeared to be optimum was found. The composition of this alloy and an approximate comparison of its properties with two commercial alloys are presented in tabular form.
