Bending fatigue behaviour of shot peened Al-Li 8090T3 thin plates

In this study, the effect of shot peening on fatigue life of Al-Li 8090T3 thin plates, which are used in the production of structural components of high-speed ships, is investigated. It is shown how various manufacturing procedures influence fatigue life of shot-peened material. Surface cleaning and protecting have a low impact on fatigue life Al-Li 8090, while cold rolling considerably improves the number of cycles that thin aluminium plates can endure. NC machining and surface polishing resulted in significant increase of the fatigue life. The experiment has shown that an adequately chosen shot peening parameters in a combination with favourable manufacturing procedures, like NC machining, may result in an increase of the fatigue life of more than 50 %. It can be concluded that shot peening improves fatigue life of Al-Li 8090 T3 thin plates.
