The book focuses on the effects of shock waves on vacancies and their clusters in fcc crystals. It is shown that high-speed cooperative atomic displacements represent a powerful tool for the purposeful modification of defect structures in crystalline bodies. The results are important for radiation material science, nano-engineering, the study of shock wave effects and the ultrasonic treatment of materials.
