阐述了激光冲击强化(LSP)技术定量调控表面残余应力的最新研究动态,重点论述了激光冲击研究中的主要问题,指出激光与材料相互作用、表面残余应力、微观组织变化多尺度表征是激光冲击强化技术研究的新热点。在此基础上,对激光冲击强化技术在表面残余应力定量调控和海洋工程重型装备制造中的应用进行了展望。
The latest research trends on the quantitative regulation and control of surface residual stress by laser shock enhancement (LSP) technique are expounded. The main problems in laser shock research are discussed emphatically. The multi-scale characterization of the interaction between laser and material, surface residual stress and microstructure is laser shock Strengthen the new hot spot of technology research. On this basis, the prospect of laser shock strengthening technology in the quantitative regulation of surface residual stress and the application of marine engineering heavy equipment manufacturing are prospected.
