In this work, the effect of aging variables of a proposed heat treatment
and their combined impact on the fatigue life of an Al6061-T6 were
evaluated. Al 6061-T6 specimens were prepared according to the ASTM E466
and then heat-treated, followed by fatigue tests in a rotating beam
testing machine. The results showed an increase in the fatigue life of
Al6061-T6 up to 4.47 times and up to 4.69 regarding the aging
temperature and the aging time, respectively. Three empirical models to
estimate the fatigue life in function of the aging time, aging
temperature, and both aging time and temperature were obtained by
fitting the experimental, showing a correlation of R 2 =90%, R 2
=79.2%, and R 2 =80.1%, respectively. The proposed heat treatment also
decreased the energy consumed by the process by 67.8% than that
consumed by the T6 heat treatment of the raw material as a consequence
of reducing the time of the process.
