Abstract
The knowledge of the flow behavior of metallic all
oys subjected to hot forming
operations is of particular interest for designers
and engineers in the practice of industrial forming
processes simulations (i.e. rolling mill). Nowadays
dynamic recrystallization (DRX) is recognized
as one of the most relevant and meaningful mechanis
ms available for the control of microstructure.
This mechanism occurs during hot forming operations
over a wide range of metals and alloys and it
is known to be as a powerful tool which can be used
to the control of the microstructure and
properties of alloys. Therefore is important to kno
w, particularly in low stacking fault energy (SFE)
materials, the precise time for which DRX is availa
ble to act. At constant strain rate such time is
defined by a critical strain,
. Unfortunately this critical value is not directly
measurable on the
flow curve; as a result different methods have been
developed to derive it. Focused on steels, in the
present work the state of art on the critical strai
n for the initiation of DRX is summarized and a
review of the different methods and expressions for
determining
is included. The collected data
is suitable to feeding constitutive models.
