The structure and texture of the molybdenum sheet after hot rolling at a temperature of 1100 °C with a total degree of deformation exceeding 90 % was investigated by orientation microscopy using electron backscattered diffraction (EBSD). As a result, hot deformation structure has been formed over the entire thickness of the sheet, consisting of elongated polygonised grains. It has been found that the texture throughout the thickness of the sheet consisted of a set of orientations stable during rolling deformation: strong (010)[¯101] and weaker - two of the {112}, two of the {111}, and two of the {111}. Recrystallization texture formed during annealing of the molybdenum plate at 1200 °C consisted of the same set of orientations as the deformed grain structure after hot rolling. In the process of recrystallization the orientation (010)[¯101] weakened, and the other orientations intensified. It is shown that the orientation of recrystallized grains is linked with orientations of deformed grains by turns at certain angles around crystallographic axes . The formation of recrystallization texture can be explained by the movement of special boundaries of Σ9, Σ11 types, the appearance of which preceded the formation of the relevant special misorientations between the components of the deformation texture.
