From: Microstructural deformation process of shock-compressed polycrystalline aluminum
Williamson-Hall analysis of shock compressed polycrystalline aluminum. (a–d) Width distribution of the Bragg diffraction peak of the 111 aluminum reflection along the radial direction at ambient pressure (black curve) and at delay time of −3, 0, 3 and 6 ns (red curves). All data points of the Bragg diffraction spots were obtained from the average of 25 diffraction images. The Bragg diffraction spots broaden with shock wave loading. (e) Time-evolution of the center of the peak width distribution of the 200 reflection. (f) Williamson-Hall plot of aluminum during shock compression at 6 ns. The dotted line was fitted to the shock compression data using Eq. (3).
