Abstract
TEMPERATURES as low as –60° C. may be reached by parts of the structures of aircraft flying at great heights. S. J. Rosenberg (J. Res., Nat. Bur. Stand., 25, 673; 1940) has examined the effect of low temperatures, down to –78° C, upon the tensile properties, hardness, and impact resistance of metals commonly used in building aircraft. For the materials tested, including ferritic steels, austenitic stainless steels and nickel alloys and light metal alloys (Aland Mg-base), #none of these mechanical properties was adversely affected by low temperatures with the exception of a decrease in impact resistance of ferritic steels as the temperature fell. In common with all papers published in this journal, the present paper may be bought as a separate reprint (Research Paper R.P. 1347), from the Superintendent of Documents, U.S. Government Printing Office, Washington, D.C.
