摘要：

The cyclic deformation behavior of deep rolled and polished aluminium wrought alloy AlMg4.5Mn has been investigated in the temperature range from 20 to 300degreesC. 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. (C) 2004 Elsevier B.V.
