Abstract
The deep-rolled aluminum alloys AA5083 (Al-Mg-Mn) and differently aged AA6110 (Al-Mg-Si-Cu) were cyclically deformed particularly in the low cycle fatigue regime for different temperatures up to 250 degrees C as compared with the polished condition. The effective boundary of deep rolling was investigated and analyzed using s/n data and the stability of near-surface residual stresses and work hardening. It was found that the near-surface work hardening is the major factor influencing the fatigue lifetime of the deep-rolled aluminum alloys. (c) 2007 Acta Materialia Inc. Published by Elsevier Ltd.
