Associated with this aging process is a change of mechanical properties as well as a change of damage mechanisms. Within the scope of the FVV project Aging and Lifetime, Fraunhofer IWM in Freiburg and BAM in Berlin (both Germany) experimentally characterized the widespread high-temperature aluminum alloy EN AW-2618A in different over aging states. Based on the experimental findings, models for numerical lifetime assessment with the finite-element method were implemented.enaluminum alloy EN AW-2618Afatigueload collectives620621journal article
