Outline of Final Research Achievements |
Ultrafast time resolved in situ X-ray diffraction measurements for shock-compressed materials were carried out by using an X-ray free electron laser. Laser-induced shock compression experiments were conducted using 3-ns pulse width high-power pump laser, and in situ observation measurements were carried out using 10-fs pulse width XFEL probe. A time series variation in lattice parameters and nano-crystallization of polycrystalline corundum was observed for 10 ns during shock-wave propagation. This result sheds light on our understanding elastovisco-plastic transition, nano-crystallization, and micro futures in brittle materials.
