DETERMINATION OF MATERIALS DESIGN CRITERIA FOR 6Al-4V TITANIUM ALLOY AT ROOM AND ELEVATED TEMPERATURES. Period covered Junuary 1956 to May 1958
In order to establish design criteria on the 6A1--4V titanium alloy, tensile, compressive, bearing, and shear properties have been determined on both bar and sheet material at temperatures from 75 to 1000 deg F. In addition, tensile properties of sheet material were determined after 100-hour exposure at 600, 800, and 1000 deg F. Test results were compared with recently established minimum requirements for tensile strength in order to derive design values for compression, bearing, and shear. Other properties investigated include minimum bend radius for 105 deg bend and notched tensile strength at temperatures from 75 to 1000 deg F, and torsional properties at room temperature. Axial load fatigue characteristics were investigated at temperatures from 75 to 1000 deg F for both smooth and notched specimens at stress ratios of 0 (stress-rupture), 0.3, 1.0, and infinity. Descriptions of the test specimens, equipment, and procedures used are included. Test results are reported in tables and in curves showing the effect of temperature on the various mechanical properties. (auth)
