The metal material is treated by adopting a method of continuously and alternately acting high-energy pulse heat load and laser impact force load, thermal stress and electronic wind power are introduced into the material by utilizing a high-energy pulse current transient thermal effect, the flow stress of the material is reduced, and the plasticity of the material is improved.

Description

technical field [0001] The invention belongs to the field of laser non-traditional processing and manufacturing, and particularly relates to the field of multi-process compound processing and manufacturing. It discloses a device and method for continuously and alternately impacting metal materials by using pulse current thermal loading and laser impact force loading, specifically a thermal load Device for continuous alternating impact strengthening and its working method. Background technique [0002] A large number of metal materials are used in key parts such as aircraft and aero-engines. The main failure modes of metal materials, fatigue and corrosion, occur on the surface of the material. Therefore, the surface structure and performance of the material directly affect the comprehensive performance and application range of the material. Laser shock strengthening technology uses strong laser-induced shock waves to act on the metal surface to cause plastic deformation of th...
