Abstract Fretting fatigue experiments were conducted on flat fretting junctions of 1040 steel subjected to axial cyclic zero-tension-zero-type loading. It was found that fracture often occurred in the central part of the fretted area and metallographic examination showed this was then associated with the high degree of mechanical damage of that zone. Caverns of martensite were found in the damaged region. The presence of the martensite indicates that temperature peaks of over 850 °C occur locally on the fretted surface. Fretting fatigue cracks were observed to originate from the martensitic structure.
