Abstract
High strength steels, as used in technical springs, are subjected to very high numbers of cycles (in the regime of one billion) during service. At such high numbers of cycles, fatigue fracture may occure stating at small materials inhomogeneities. These inhomogeneities may be non-metallic inclusions, large grains or surface defects (caused by machining or corrosion). The influence of inhomogeneities is investigated experimentally within the project, and lifetimes are described using appropriate models, such as fracture mechanics.
