PREDICTION OF FATIGUE LIFE FOR AL8090 REINFORCED WITH TITANIUM DIBORIDE AND GRAPHENE COMPOSITE.

The fatigue performance of cast Al8090 alloy added with titanium diboride and graphene was examined. Al8090 is a widely utilized material in the aviation sector, recognized for its distinctive attributes such as decreased weight, increased stiffness, and superior fatigue resistance. These attributes render it ideal for high-performance and weight-sensitive applications, especially in aircraft structures and components. Fatigue tests controlled by stress and strain were performed to determine the fatigue strength. The performance of high-cycle fatigue was empirically investigated at several levels of stress concentration. The findings indicated that incorporating titanium diboride and graphene improves fatigue resistance.
