激光喷丸塑性成形金属板料是从激光强化发展起来的新技术。当激光诱导冲击波的峰值超过材料的 动态屈服极限时，板料冲击区的表层发生微观塑性变形，导致了板料厚度方向上不均勻应力分布，使板料发生 宏观变形。不同的激光脉冲参数在板料内部产生不同的残余应力，不同的残余应力使板料发生不同的变形，通 过控制喷丸的工艺参数来控制板料内部应力场的精确分布，就可实现板料的精确变形。其显著特点是成形精确， 且表层留有有益的残余压应力。

Laser peening forming is an emerging modern process developed from laser shock strengthening. During a laser peening event, pressures well above the dynamic yield strength of the material are imparted to the target in a fraction of nanoseconds. The severity of the loading causes local plastic deformation which ultimately results in the development of the uneven residual stress along the thickness of plate, which pushes the plate to deform. Different parameters of laser can induce different residual stress which make plate achieve different shapes, so controlling technical parameters of laser peening can control the distribution of residual stress, indirectly controlling the deformation of plate to satisfy its design. Laser peening forming is a flexible technology, which can form tight radii in thick material with high accuracy and compressive stress into its surface to extend fatigue lifetime. In the end of the paper, the application prospect of technology is outlined.
