The Selection of Metals for Airframe Components as Affected by Operation at Elevated Temperatures up to 600 F

THE effects of elevated temperatures up to 600 F on the mechanical properties of common structural materials are treated briefly.

The shortcomings of both short- and long-time exposure data are set forth, as are the inadequacies of present methods of analyzing certain members of aircraft structures. The changes in material properties at the higher temperatures and the manufacturing considerations relevant to material selection, such as cost, formabiliry, and availability, are mentioned as a part of the design problem in general as regards aircraft structures.
