Most of the cases the operator has to use a reverse engineering process for each alloy, varying
the constant value, up the point where the forecast deficiencies matches those validated into
practice, through castings of the same composition already manufactured.
Some of these values are sometimes found by reverse engineer process.

Abstract.
There are different methods to form ultrafine grained ferrite (α), mainly based on sever plastic deformation or advanced thermomechanical processes.
Advanced thermomechanical processes like hot rolling in the intercritical region [4], strain induced ferrite transformation [5] or dynamic recrystallization (DRX) of the ferrite during warm rolling [6] require true strain of about 2 to 3.6 to form ultrafine grained ferrite ranging from 1-5μm, which is comparative to the applied strain in SPD methods.

Abstract.
The GI condition, which is also the ‘as-delivered’ condition of the steel from a steelmaker to automakers shows similar engineering stress-strain curve as the HPF condition, giving similar tensile properties.
SEM micrograph and retained austenite fractions (XRD) of the medium Mn steel in (a) GI condition and (b) after hot forming at 675 oC; (c) comparison of the engineering stress-strain curves of the GI and hot formed (675o) medium Mn steel and a conventional 1000 MPa HPF steel based on ‘boron alloying’ concept.
