Processes of structure and texture formation in hot rolling of electrical anisotropic steel are studied. It is shown that the structure of the surface layers of hot-rolled strips forms as a result of the joint action of γ → α phase transformation and dynamic recrystallization. The structure of the central layers forms as a result of recovery of deformed grains.

St is well known that with reduction in thickness for sheet steel ( , becomes less stable. This effect has not yet been sufficiently explained. It is assumed that an increase in the ratio of steel surface area to its volume leads to weakening of the effect of inhibiting normal grain growth and the primary recrystallization texture [2].

1. External stress applied to a specimen during the bainitic transformation causes significant acceleration of this process and a reduction in its incubation period. An axial 〈110〉α texture forms when the transformation takes place under tensile stress. 2. Preliminary thermal deformation of austenite in the region of its maximum stability (or a developed dislocation structure) gives rise to braking of the bainitic transformation. During the transformation of austenite deformed by rolling, its texture is transformed into a {112}〈110〉α texture. 3. An external stress that acts during the transformation of deformed austenite places additional constraints on the process of the γ→α lattice reconstruction. Those bainite crystals, during whose formation shear occurs along the planes with the maximum tangential stresses, receive preference. 4. A {112}〈uvw〉α texture, which contributes to an increase in property isotropy in the plane of rolling, is formed LTMIST with transformation under tensile stress parallel to the direction of rolling.

1. Preliminary annealing of deformed metal has a marked effect on the amount of (100)[OVW2 cubic component of the structure formed during subsequent high temperature annealing. 2. Preliminary annealing at 500°C for 1.5 h and 600°C for 30 min causes an increase in (100)[OVW] component to 50% during subsequent annealing at 900°C for 2 h. 3. The reason for the increase in cubic component (100)[OVW] after optimum preliminary annealing and final annealing at 900°C for 2 h is probably partial retention of deformed (100)[011] grains and the occurrence of an increased amount of (100)[OVW] during primary recrystallization.

1. In chromium-nickel corrosion-resistant strip prepared by the standard technology a secondary recrystallization texture (100) 〈100〉 forms. 2. A correct degree of deformation and heat-treatment schedule selected in production of cold-rolled strip makes it possible to obtain a texture (113) 〈112〉, (120) 〈100〉 with favorable elasticity property anisotropy for deep drawing.

1. A heating rate of 20 deg/h ensures good formability for deep drawing of steel stabilized with aluminum. 2. The aluminum content affects the texture formation and thus the changes in the mechanical properties during annealing. Better mechanical properties and crystallographic texture favorable for good formability were obtained for the steel with 0.055% Al than for the steel with 0.012% Al.

1. The atmosphere of high-temperature annealing has a substantial effect on the growth rate of secondary recrystallized grains. 2. The oxygen concentration is the determining factor in the effect of the annealing atmosphere on the process of texture formation in electric sheet. 3. The maximum perfection of the edge texture in electric sheet is achieved by annealing in hydrogen with a dew point of −80°C.
