ABSTRACT Fretting fatigue can be a serious problem for many engineering applications. Relative motions between components in contact can generate surface and subsurface damage, which leads to failure of the component. Hence, it is very reason that the microstructural condition strongly influences the so-called fretting fatigue behaviour. Nevertheless, the microstructural influence on the fretting fatigue behaviour is not very well investigated up to now. To investigate systematically the influence of specific microstructural parameters on the fretting fatigue behaviour, a broad variety of different iron-base materials were selected for this study. Based on a variation of the grain size and of the ferrite/pearlite morphologies, a detailed understanding of microstructural effects on the fretting fatigue behaviour can be derived. In general a reduction on the fatigue life compared to uniaxial fatigue tests by up to 50 %, depending on the respective microstructure, normal load and strain amplitude, was observed.
