Fatigue Behaviour of Aluminum Alloy at Elevated Temperature

Abstract

In this article fatigue behavior of aluminum alloy at elevated temperature is studied. Fatigue failure is a major failure mode of failure where the cyclic load is applied to the machine element. Hence certainly it is important to know the fatigue behavior of the machine element at elevated temperature, aluminum alloy is excessively used in industry like in aerospace automobile and miniatures industries etc, because of it s non corrosive property and light in weight. The fatigue behavior of 2024 – T4 Aluminum alloy is investigated under room and elevated temperatures and it is observed that the fatigue strength of 2024 – T4 Aluminum alloy at elevated temperature is reduced by a factor 1.2 – 1.4 compared with dry fatigue strength.
