Effect of Orientation Selection Scheme of Nucleus on Discontinuous Dynamic Recrystallization: Analysis with Multiscale Modeling Approach

نویسندگان

چکیده

Effect of crystallographic orientation nucleus on discontinuous dynamic recrystallization (DDRX) behavior in 304LN stainless steel is investigated using a multiscale model, namely coupled crystal plasticity finite element method and DDRX-based cellular automata model. The three selection schemes are specially exploited the simulation; i.e., (1) random orientation, (2) inheritance parent deformed grain, (3) generalized strain energy release maximization theory. DDRX behaviors such as flow stress, volume fraction, grain size, texture predicted by compared differences explained through simulated microstructure evolutions. This study suggests that it reasonable to assign comparisons with experimental evidence.

Analysis of Dynamic Recrystallization of Ice from EBSD Orientation Mapping

We present high resolution observations of microstructure and texture evolution during dynamic recrystallization (DRX) of ice polycrystals deformed in the laboratory at high temperature (≈0.98Tm). Ice possesses a significant viscoplastic anisotropy that induces strong strain heterogeneities, which result in an early occurrence of DRX mechanisms. It is therefore a model material to explore these...
