| Abstract: | The feasibility of improving the vibration fatigue performance of K417 alloy by laser shock processing and aluminizing was studied. The result shows that the vibration fatigue performance of K417 alloy is effectively enhanced by laser shock processing and aluminizing. The specimens were analyzed by SEM and TEM, and the mechanism of the vibration fatigue performance improvement was discussed. |
