Microstructure evolution and softening processes occurring

The current work investigates the microstructure evolution and softening processes that take place during annealing of an austenitic Ni-30Fe model alloy subjected to hot deformation in the dynamic recrystallization (DRX) regime.The substructure of the deformed matrix grains largely comprised organized microband arrays,though that of the DRX grains consisted of more random,complexMicrostructure evolution and physical-based diffusion Dec 15,2019 microstructure evolution and dynamic softening mechanism#0183;Such a microstructure evolution with continuous rotation of subgrains is the feature of CDRX.With the increase of strain as shown in Fig.5(cd),more subgrains and DRX grains can be observed,implying dynamic softening is enhanced.The subgrains rotate progressively followed by the further increase of misorientation.Microstructure evolution and dynamic softening mechanisms Sep 01,2018 microstructure evolution and dynamic softening mechanism#0183;Dynamic softening mechanism and the effect of primary precipitates at the boundaries on microstructure evolution were identified.For the coarse grain,the nucleation of DRX grains was identified to be influenced by the precipitates spacing .From the above inferences,it is obviously that several works concerning the mechanisms of DRX nucleation as well as the correlations between coherent precipitates and DRX microstructure evolution
