Fatigue of deep rolled AlMg4.5Mn (AA5083) in the temperature range 20–300 °C

The cyclic deformation behavior of deep rolled and polished aluminium wrought alloy AlMg4.5Mn has been investigated in the temperature range from 20 to 300 °C. Results of quasistatic tension and compression tests of untreated specimens are presented. To characterize the fatigue behavior for stress-controlled tests as a function of test temperature, stress-life-curves, cyclic deformations curves and mean strains as a function of number of cycles are given. Residual stresses and work hardening effects near the surface of the deep rolled condition before and after fatigue tests were investigated by X-ray diffraction methods.
