Design of a forging process to individually examine thermal, mechanical and tribological stress in the tool surface zone

authored by: Bernd Arno Behrens, Felix Müller, Uwe Lorenz
Abstract: The surface layer of hot forging tools undergoes local microstructural changes due to high thermo-mechanical and tribological loads. Tools made of hot working steel are usually preheated and experience extreme heating and cooling during each forging cycle, affecting their local wear behaviour significantly. Therefore, the analysis of these tool surface layers in die forging and their effect on wear behaviour is of great importance. The microstructural changes in the tool surface layer mainly depend on thermal loads, which are highly influenced by the tool cooling system. A process and a suitable tool system are developed to vary the thermal and mechanical loads on the tool surface layer and fundamentally examine the resulting microstructural changes.
