Abstract
It is well known that surface energy anisotropy is one of the driving forces for the orientation selection at the metal-vapour interface. This affects the microstructure and texture evolution at the surface during phase transformation, which is an inherent feature of low-alloyed low-carbon steels. This paper investigates the nucleation and growth of the surface texture by orientation contrast microscopy. It has been found that the surface texture is dominated by {001} oriented grains, which exhibit a remarkable orientation gradient from the centre of the grain towards the edge. The {001} oriented grain centre gradually rotates around a < 110 > axis in small incremental steps when nearing the edge of the grain. Towards the edge the accumulated rotation angle has commonly reached a value of 30 degrees. Underneath the surface grains (similar to 30 mu m) the bulk texture consists of a strong gamma-fibre.
