Peen forming process is a kind of forming method which uses the high speed metal pellet to spray metal plate surface, which causes the surface material to produce plastic deformation, resulting in the residual stress field and the curvature of the shape.
The high speed metal pellets spray onto the plate surface, which causes the surface material to produce plastic deformation and pits, and the surface area of metal plate is increased, so that compressive stress is generated in the tangential direction of the plate surface. A large number of metal pellets produce numerous pits on the surface of plate, and the indentations overlap each other, the surface material of a certain depth is extended, resulting in the surface area to be increased, and the metal plate is bent and deformed.
Peen forming process has strong adaptability which also can keep the part material properties and surface integrity. Meanwhile, the strengthening effect will improve the fatigue performance and the overall performance.
