Deformation and fracture behavior of tungsten-5% rhenium and unalloyed tungsten under dynamic tensile loading

Conference ·
OSTI ID:10119989
The deformation behavior and ductile-brittle transition temperatures (DBTT) of unalloyed tungsten and a tungsten-5% rhenium alloy were investigated under quasi-static and dynamic loading conditions. Both test materials were tested in the warm-worked/wrought microstructural state. Testing was performed over a range of temperatures from 23{degree}C to 450{degree}C. In this work, the DBTT was defined as the test temperature at which ductile (necking) failure of the test sample is expected. Consistent with other studies reported in the literature, the tungsten-5% rhenium alloy has a considerably lower DBTT than the unalloyed material under quasi-static loading. In contrast, under dynamic loading the tungsten-5% rhenium alloy and the unalloyed material similar ductile-brittle transition behavior.
