Abstract

In this work, a qualitative assessment of the influence of heat treatments sequence on Al6061-T6 fatigue behavior was performed. The aluminum alloy was, on one hand, subjected to a set of designed heat treatments of aging, retrogression and reageing and then tested in a rotating beam fatigue machine; on the other hand, temperature evolution of specimens under fully reversed rotating beam cyclic loading was measured through an infrared thermographic camera. The evolution of temperature and its relationship with the fatigue life was discussed. Factographies were done as a complement in order to have visual evidence of the effect of the heat treatments on the nucleation and propagation of the fatigue crack. Evidence of the relationship between the fracture crack growth and the steady-state temperature of the tests was observed.
