Notes:
The simultaneous influence of both thermal and mechanical treatment was applied toproduce a geometrically complex shaft from 51CrV4 steel. This special treatment led to theformation of adjacent microstructures which were significantly different from each other. It wasfound that these microstructural changes were accompanied by a change of mechanical properties interms of hardness, electrical resistivity and especially internal friction. Specimens for structuralstudies and study of mechanical and physical properties were taken out from different places of theproduced shaft and tested in order to verify and understand the obtained gradation. The significantvariations in properties could be explained in terms of structure and dislocation behaviour underapplied cyclic stress using mechanical spectroscopy technique. The cold-work (Snoek-Köster) peakwas recognised and analysed in the structure of this steel
