Abstract: Recovery based observations of behavior in Ta generated under high pressure loading conditions are reported. Two shock pressures, 25, and 55 GPa and four orientations {(100), (110), (111), (123)} were considered. Recovered samples were characterized using electron backscatter diffraction along with a limited amount of transmission electron microscopy to assess the occurrence of twinning under each test condition. Material recovered from 25 GPa had a very small fraction of twinning for the (100), (110), and (111) oriented crystals while a more noticeable fraction of the (123) oriented crystal was twinned. Material recovered from 55 GPa showed little twinning for (100) orientation, slightly more for the (111) orientation, and a large area fraction for the (123) orientation.
