FIG. 1.

(Color online) (a) Schematic of the laser pump-X-ray probe scheme to measure time-resolved x-ray polycrystalline diffraction of laser-shocked sample. (b) Target assembly used to confine laser-generated plasma and produce pressure pulse in the sample.

Image of FIG. 2.
FIG. 2.

(Color online) (a) Two dimensional diffraction pattern of the pristine sample recorded on the CCD camera. The square shadow is due to the shield for stopping the laser beam to the CCD camera. (b) The diffraction intensity profile as a function of 2θ obtained by azimuthally averaging the Debye–Scherrer pattern. The marks below the profile show the peak positions of the tetragonal phase.

FIG. 3.

(Color online) Normalized intensity profiles of shocked 3Y-TZP in the cases of Δt = 15 ns (a) and 1005 ns (b) and correspondent intensity changes (c) and (d). Two series of bars at the bottom of (a) and (b), respectively, show the calculated diffraction peaks of the monoclinic and tetragonal phases. Thesubscripts M and T represent the monoclinic and tetragonal phases, respectively.

Image of FIG. 4.
FIG. 4.

(Color online) Normalized intensity change as a function of the delay time Δt, demonstrating the time evolution of structural dynamics of the laser-shocked 3Y-TZP. The dashed lines indicate the position of observable new diffraction peaks corresponding to the monoclinic phase.

Image of FIG. 5.
FIG. 5.

Diffraction peak shift of the crystal plane (011) and deduced relative interplanar spacing change as a function of the delay time Δt ranging from 25 ns to 1005 ns.
