The etch-pit method is a useful technique for studying the grain orientation in polycrystal line materials. In this paper, the etch-pit method is extended to obtain a quantitative analysis of the texture of materials. From the experimental results, the orientation distribution function (ODF) and the misorientation distribution function (MODF) can be calculated. The computer program developed for this analysis returns the grain size distribution of different texture components and the frequency of coincidence site lattice (CSL) boundaries, as well as other data. This information is used to analyse the grain growth and texture development in transformer steel.
