摘要
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 newest research status of using laser shock processing （LSP） technology to quantitatively control the surface residual stress is elaborated, and the major problems in laser shock studies are specially discussed. It is pointed out that the laser interaction with materials, surface residual stress, and multi-scale characterization in microstructure changes are the research hot spots in the field of LSP technology. Based on these, the prospect for the application of LSP technology in the quantitative control of surface residual stress as well as in heavy marine equipment manufacturing is conducted.
