ULTRA-SHORT-TIME CREEP RUPTURE

Abstract

The design and fabrication of ultra-short-time creep test equipment and tilization of the equipment for determining the short time mechanical properties of a structural refractory metal sheet alloy at elevated temperatures was studied. Tensile test specimens of Ta-10%W alloy were strained at temperatures of 2000, 2500, 2750, and 3000 F in an argon atmosphere and in a vacuum (3000 F only). Heating of test specimens to maximum temperature was accomplished in approximately 60 msec. Tensile loading of test specimens at each temperature was acomplished prior to attining test temperature and 1/2, 2.0, and 5.0 sec after attaining test temperature. A desription of test apparatus, test procedures and complete test data are given. (Author)
