Crystallographic Characteristics and Elastic Strain in Pearlite Structure

True Stress–True Strain Relationship up to the Plastic Deformation Limit in Ferrite–Pearlite Steel at Various Temperatures

“…26,27) Several colonies in which pearlite structure has the same longitudinal direction were observed within one block with the identical crystallographic orientation. 24,28) In the SEM images, both the microcrack and their aggregations were observed. From the orientation color maps, the crack with large opening and the junction of these cracks with different elongated directions accompanies with color-gradient indicating large local misorientaions.…”
