Paragraph starter
The nucleation of new phases during solid-state transformations is critically influenced by crystallographic factors. Research indicates that the specific orientation of the parent austenite phase dictates preferential sites for ferrite nucleation, suggesting that controlling crystallographic texture during processing can lead to predictable microstructural evolution and, consequently, tailored material properties.
