Continuous dynamic recrystallization during the transient deformation in a Ni-30%Fe austenitic model alloy
The substructure development during dynamic recrystallization (DRX) of an austenitic Ni–30%Fe model alloy was investigated using a transient deformation testing with a discontinuous increase in the strain rate. The current results revealed that two types of DRX mechanisms, i.e. the discontinues DRX...

| description | The substructure development during dynamic recrystallization (DRX) of an austenitic Ni–30%Fe model alloy was investigated using a transient deformation testing with a discontinuous increase in the strain rate. The current results revealed that two types of DRX mechanisms, i.e. the discontinues DRX and the continuous DRX, may operate, which are closely associated with the deformation history. The preserved substructures developed in former deformation stages can facilitate the strain-induced subboundaries increasingly transforming to higher-angle boundaries in further straining after the strain rate abruptly increased, which promotes the occurrence of continuous DRX in the austenitic alloy. |
