Thermo-Mechanical Influence on the Internal Friction of a 51CrV4 Shaft

The influence of simultaneously applied mechanical and thermal treatment is used for producing a geometrically complex shaft from 51CrV4 steel resulting in widely differing formations of microstructures. Materials' properties such as internal friction (IF), hardness and electrical resistivity are affected by this change of microstructure formations. The Snoek–K?ster peak is identified and analyzed in the actual steel structure.
