Revealing secrets of material behavior at extreme conditions
While exposing a sample of silicon to extreme dynamic compression–due to the impact of a nearly 12,000 mph plastic projectile–WSU scientists documented the transformation from its common cubic diamond structure to a simple hexagonal structure. At one point, they could see both structures as the shock wave traveled through the sample in less than half a millionth of a second.
WSU led the development of this experimental capability, which allows scientists to watch atomic-level changes unfold in the composition and behavior of materials under extreme conditions. Experiments take place in a facility called the Dynamic Compression Sector … » More …
