In order to investigate the effects of grain boundaries on the cold-rolling and recrystallization textures, two samples which had different grain sizes of 40μ and 270μ in diameter, were prepared by using a zone-melted high-purity iron. These samples were hot-forged and hot-rolled to the plates of 2mm in thickness. These plates were cold-rolled to the sheets of 0.5 mm in thickness by 75% reduction and annealed isothermally at 500℃ or 575℃ in salt bath. X-ray pole-figure measurements, optical and electron microscopic observations were made for the specimens of as cold-rolled and as annealed conditions. Cold rolling texture : In the coarse grain specimen two types of fiber texture exist, one has a <111> fiber axis parallel to the sheet normal and another has a <110> fiber axis parallel to the rolling direction, and the dominant texture component is {111}<112>. In the fine grain specimen, texture has a <110> fiber axis parallel to the rolling direction and the major component of the texture is {001}<110>. In the microscopic observation, continuous change of orientation from {001}<110> to {111}<110> is often observed in the whole area of specimen. Recrystallization texture : In the coarse grain specimen, {110}<001> texture component is preferred and the texture component of near {111}<112> coexists. In the fine grain specimen, {111}<110> texture component is dominant. At the beginning of recrystallization, {111}<110> recrystallization nuclei in {001}<110> matrix are found frequently in electron microscopic observation.
