Deformation texture of 90% cold rolled iron of various purities was studied by pole figure measurements from which complete orientation distribution functions ODF were calculated using series expansion including the zero range method. The texture type consists of two mutually perpendicular orientation tubes which can be idealized as ( 110 )//RD and ( 111 )//ND in accordance with microstructural investigations which revealed two types of microstructures corresponding to these idealized fibres. The intensity superposition of the two fibres yields a maximum density in slightly deviating positions especially in the vicinity of the intersection of the two tubes which may be idealized as ( 110 ) 30° ND fibre component. The texture of the high‐purity iron is nearest to the ( 111 )//ND fibre. Within this general texture type, two subtypes can be distinguished corresponding to high‐purity iron on the one hand and the low‐purity materials on the other. The texture of the high‐purity iron at 90% of deformation still corresponds to the low‐degree type of the lower‐purity materials which is attributed to the occurrence of dynamic recovery in the high‐purity iron.
