title = "Dwell-fatigue behavior of a near α Ti 6242 alloy",
abstract = "For over three decades, aeroengine manufacturers are confronted to the phenomenon of room temperature dwell-effect consisting in a decrease in structure life due to the introduction of hold periods at the maximum stress of the pure cyclic loading waveform. Even if many studies have been conducted to analyze the parameters responsible of this life decrease the so called {"}dwell effect{"} remains not completely understood. The present paper focused on damage occurring during pure cyclic, dwell fatigue and creep tests on a β-forged Ti-6242 alloy. It results from SEM and TEM analysis that crack initiation occurs by coalescence of shear-induced cavities nucleated at α/β interfaces in large colonies of α laths nearly parallel to the loading axis. The density and average size of cavities were larger in dwell-fatigue and creep than in fatigue.",
