MICRESS Forum

Hi. In the acicular ferrite example for Micress, there are two possible orientations taken by the acicular ferrite grains in one austenite grain, as shown in the attached image. Is there a way to restrict this possible orientation to one single value in one grain?

The aciculare ferrite can nucleate in two different variants, because both variants are equivalent in cubic austenite.
If you want to obtain just one of the two variants you can reduce the symmetry of austenite from 'cubic' to 'tetragonal' or 'none'.
