Flow stress prediction during intercritical deformation of a low-carbon steel with a rule of mixtures and Fe-simulations

摘要

Implementation of the Bergstrom work-hardening model into an FEM code enabled simulating the deformation behaviour during intercritical deformation of a low-carbon steel. The simulations revealed that the conventional mixture rule overestimate the FE predictions as well as actual measurements. Slip lines under 45 deg are predicted once the microstructure is inhomogeneous.
