DETERMINATION OF THE TENSILE, COMPRESSIVE AND BEARING PROPERTIES OF FERROUS AND NONFERROUS STRUCTURAL SHEET MATERIALS AT ELEVATED TEMPERATURES. Period covered: June 1955 to July 1956
To provide data for the establishment of design criteria, the compressive and bearing properties of six Al alloys, three Mg alloys, two Ti alloys, two stainless steels, and one alloy steel have been determined at elevated temperatures. Tensile dnta were also obtained for all materials except the stainless steels. Each material was tested at several temperatures as follows: 2014-T6, 7075-T6, and X7178-T6 Al alloys and M1-H24, AZ31-H24, and AZ31- 0 Mg alloys at 200, 300, 400, 500, and 600 deg F; 2024-T3 Al alloys at 212, 300, 400, 500, 600, and 700 deg F; 2024-T81 and 2024-T86 Al alloys at 200, 300, and 400 deg F; annealed Ti, cold-rolled Ti, Type 301 half-hard stainless steel, Type 302 annealed stainless steel, and SAE 4130 alloy steel at were aged for 0.5 hr at test temperature prior to testing. The test materials used in the program were leftover portions of sheets which had been tested previously. They had been in storage for periods ranging from 3 to 5 yrs. Analysis of the test data suggested that long room temperature aging has a substantial effect on the elevated temperature properties of certain hard-rolled and heattreated alloys. The properties of the fully annealed materials, however, appeared to be unaffected by protracted aging at room temperature. Test specimens, equipment, amd procedures are described in detail, and test results are presented in both tabular and graphical form. (auth)
