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.

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.
