【Abstract】 The rapid development and application of ultrasonic shot peening in recent years are reviewed. Surface nanocrystallization, improvement of metal material performance and sheet metal forming are finished by the ultrasonic shot peening. This kind of technology has been widely applied in many fields due to its convenient operation, sound repeatability, no pollution and little noise. This paper induces the research status and engineering applications of the ultrasonic shot peening technology at home and abroad, and then the strengthening mechanism, surface nanocrystallization and peening forming are introduced emphatically. Finally, the development and research trend of the ultrasonic shot peening technology are also prospected.更多还原
