α→γ→α Transformation Texture Formation at Cold-Rolled Ultra Low Carbon Steel Surfaces

Article Preview

The influence of Mn on the surface texture formation through a®g®a transformation was investigated. After the a®g®a transformation, a weak texture was formed at the surface of ultra low carbon cold-rolled sheet steel without Mn. In contrast, a sharp <100>//ND cube texture was observed in Mn alloyed ultra low carbon steel. In order to interpret the effect of Mn two alternative mechanisms were considered : (i) one assumption attributes the occurrence of the specific surface texture to the effect of outer-surface energy (ii) and according to an alternative hypothesis the release of elastic work parallel to ND in the surface area is responsible for the observed <100>//ND surface texture.
