Shock-recovery experiment can be elucidated shock-induced changes in a material at the micro level, although transient behavior of a material under dynamic compression is not studied in a direct way and pressure in the material studied is completely released. The shock-recovery experiments have been applied to a way of a material processing including structural transitions, introducing strain and defects, promoting chemical reactions, and densification. Structural transition of a material is one of an important subject for the material processing because physical properties of the material are strongly affected by its crystalline structure. Here, some examples of the shock-recovery experiments to evaluated are presented; (1) silicon and (2) gallium oxide.
