In this paper, microstructure, microhardness, and residual stress of TC17 titanium alloy treated by laser shock peening (LSP) with different laser fluence were examined and compared by x-ray diffraction, scanning electron microscope, transmission electron microscope, microhardness test, and residual stress test. The results of microstructure point out that microstrains and grain-refinement are generated in the material surface layer which is a severe plastic deformation layer. In relation to the microhardness and residual stress, the results indicate that LSP can obviously improve the hardness and introduce a great compressive residual stress which also has a good thermal stability.
