Sound velocity measurements by x-ray shadowgraph technique for melting phenomena at ultrahigh-pressure regime.

Abstract

Developments in measuring sound velocity of matter under ultrahigh pressure are described. We employed a time-resolved x-ray shadowgraph technique to measure the sound velocity of shock-compressed diamond and iron foils at around melt. The sound velocity significantly dropped at melting, a behavior that has been difficult to clarify by conventional… (More)
