Keywords： 51CrV4 steel

The simultaneous influence of thermal and mechanical treatment was applied to produce a geometrically complex shaft from 51CrV4 steel leading to the formation of microstructures which were significantly different from each other. These microstructural differences were accompanied by a local change of mechanical properties in terms of hardness, electrical resistivity and especially internal friction. The Snoek-Koster peak was recognized and analyzed in the structure of this steel.
