摘要

VISAR wave profile measurements were made on the Ti-6%Al-4%V alloy to elucidate why the Hugoniot does not extrapolate through the bulk sound speed at zero pressure. Symmetric impact experiments were performed on targets with LiF windows in the shadow region (P < 40 GPa). Large elastic waves (2.8 GPa) were observed that appeared to shock-up. The low pressure Hugoniot is given by /sup l/U/sub s/ = 5.123 km/s + 1.083 U/sub p/ for U/sub p/ < 1.4 km/s. No phase transformations were observed in this region. (ERA citation 12:041317)
