Modeling and simulation of dynamic recrystallization behavior for Q890 steel plate based on plane strain compression tests

Open Physics, 2020
In view that the traditional dynamic recrystallization (DRX) model cannot effectively predict the DRX process in the hot deformation process of sheet metal, DRX behavior modeling and simulation of q890 steel plate based on the plane strain compression ...

A critical assessment of experimental investigation of dynamic recrystallization of metallic materials

Materials & Design, 2020
Dynamic recrystallization (DRX) often takes place during hot deformation of metallic materials, which then exerts significant influence on the final microstructures and mechanical properties of the formed components.

Modelling microstructure evolution during equal channel angular pressing of magnesium alloys using cellular automata finite element method [PDF]

, 2013
Equal channel angular pressing (ECAP) is one of the most popular methods of obtaining ultrafine grained (UFG) metals. However, only relatively short billets can be processed by ECAP due to force limitation.
