Aluminum alloys are widely used in aerospace

automobile manufacturing and other fields as a common lightweight alloy. The fatigue performance

however

always restricts the application of aluminum alloy. In order to ensure the durability and safety of structural parts of aluminum alloy

it is of great significance to understand the fatigue behavior of aluminum alloy in depth and systematically. The fatigue performance of common aluminum alloys was described from the fatigue performance mechanism of aluminum alloys. The effects of the microstructure

applied load

working environment on fatigue properties of aluminum alloys were expounded

and the methods to enhance the fatigue properties of aluminum alloys were summarized

including alloying

heat treatment and surface strengthening. Finally

the future tendency on aluminum alloy fatigue was prospected.
