Influencing the evolution of damage in cold extrusion (A02)

• Subject Area: Primary Shaping and Reshaping Technology, Additive Manufacturing
• Term: since 2017
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 278868966

The aim of the subproject is to prove the hypothesis that damage can also be controlled in complex cold extrusion processes. These processes comprise a sequence of different individual operations with different stress states as well as subsequent or intermediate heat treatments. To achieve this goal, experimental and numerical studies of different fundamental tests and cold extrusion processes are conducted, using the case hardening steel 16MnCrS5. Subsequently, the separated influence of damage on the product performance is determined.
