Precipitation interactions with dynamic recrystallization of a hsla steel

摘要: Abstract A model for precipitation interactions with dynamic recrystallization is presented. It based on existing models which are modified to allow the pinning effect of precipitates. This leads an increase critical dislocation density necessary initiate and a decrease high angle boundaries velocity when compared precipitate-free systems. Dislocations have determining role kinetics as both pipe diffusion nucleation dislocations considered. Simulations been carried out experimental results obtained Mo-bearing steel compressed at 875°C. Qualitative agreement found. Most important large strain rate dependence maximum retardation intermediate rates.
