| 英文摘要 | It is a challenge to optimize the mechanical performance of high entropy alloys (HEAs). Here, we obtain yield strength enhancement along with considerable tensile ductility of CoCrFeNi HEA by laser shock peening (LSP). The surface hardness of the material is also increased significantly by 40% after LSP. Based on microstructure analysis, it is observed that the grain refinement and the mixed deformation mode of dislocation slip and deformation twin are the main strengthening mechanisms after being treated by LSP. This study demonstrates an effective method for tailoring the mechanical properties of HEAs. |
