Micromechanical Investigation of the Hot Ductility Behavior of Steel.

ISIJ International, 1999
Using a periodic microfield approach a micromechanical study is presented, which is capable to describe the ductility losses due to a film like ferrite precipitation in the high temperature region of iron based alloys by considering the two phase microstructure close to phase transformation temperatures and explicitly accounting for the elasto-plastic ...
