| 中文摘要 | The effects of laser shock processing (LSP) are studied on Vicker micro-hardness and residual stresses distributions of peened samples (TiAl) before and after treating. The specimen are treated by Nd:YAG laser system with the wavelength of 1064 nm, pulse-width of 14 ns, and pulse-energy of 2~6 J. Systematic study on the research of the micro-hardness of surface is finished, including section and single light spot of the samples peened by laser, which increase the surface hardness of TiAl alloy by 31.2%. The peak hardness is not on the surface, but inside the specimen. The distribution of single light, which is satisfied with the Gaussian distribution, in correspondence with test results of energy distribution in single light spot. |
