Abstract:

Shocked crystals were investigated by picosecond X-ray diffraction. The response of single crystal silicon to nanosecond timescale uniaxial shock compression was purely elastic. Single crystal Cu shocked along the (200) axis exhibited compression of the unit cells along both (200) and (020), indicating a transition to plastic flow.

Picosecond x-ray diffraction studies of shocked crystals

Abstract:

Experimental time-resolved X-ray diffraction data that provide firm evidence that the response of single crystal silicon to nanosecond timescale uniaxial shock compression along the (400) axis is anomalous in that it is purely elastic is presented. In addition, the results of a molecular-dynamics simulations of the diffraction of X-rays from shocked samples, which indicate that it may be possible to directly measure dislocation densities by observing the angular shifts associated with sticking faults within face-centred-cubic metals are presented as well.
