Resumo: This paper shows friction results obtained through compression ring tests for two commercially-available lubricants (i.e., Oildag and Deltaforge) applied in the hot forging of aluminum alloys. The experiments were performed with AA 6061 F aluminum alloy samples with the goal of observing the behavior of each lubricant in several conditions of temperature (200, 300, and 450 °C), strain rates (1, 10 and 50 s-1), and strain (25, 50 and 75%). The friction coefficients for each lubrication condition were established by means of calibration curves determined from finite element calculations with the use of the PEP/Larstran software package. An Analysis-of-Variance approach for the ring's internal diameter was followed in order to evaluate the performance of the lubricants. The results indicated that the Oildag lubricant presents a better stability as well as lower friction coefficients than the Deltaforge lubricant for the range of conditions tested, which translates into a better friction condition at die-part interface.
