Influence of Rolling Process on Deformation and Recrystallization Texture of Ni-Cr-Mo Alloy Tape

A two-step rolling-annealing process has been developed to increase the <111>//ND (γ fiber) component in the recrystallization texture of a copper-bearing bake hardening steel. The two step process comprises the first rolling by a low reduction in thickness and subsequent annealing at 780°C, followed by the second rolling by a high reduction and subsequent annealing at 780°C. The first rolling process aims at seeding the γ fiber oriented grains, so that they can grow at the expense of differently oriented grains developed in the second rolling process. In this way the density of γ fiber component in the recrystallization texture of the bake hardening steel much increases compared with that in the conventional one-step rolling-annealing process.

Hot Rolling Process

AbstractIn the development of an optimized hot rolling process for a Cu-Al-Ni-Mn sheet alloy, the effects of the recrystallization texture on ductility and shape memory recovery were examined. The texture of samples rolled in the β phase region (750 °C) was characterized by martensitic (128) poles along the normal direction and (0018) poles inclined 60° from the normal to the rolling direction. The texture of samples rolled in the α+β region (600 °C) was slightly stronger but less symmetric. The shape memory recovery was more or less isotropic in the rolling plane, independent of the rolling conditions. However, improved bend ductility of 9.5% was observed along the rolling direction in specimens rolled at 750 °C with a reduction per pass of 27%.

Conventional Rolling

Fe81Ga19sheets were produced by conventional rolling procedure. Recrystallization texture dominated with strong Goss ({110}) was successfully obtained through sheet thickness by primary recrystallization annealing. The development of Goss can be attributed to the favorable shear band morphology and deformation texture derived from the applied specific rolling process.

High Reduction

A new rolling process, which combined asymmetric rolling with symmetric rolling, was adopted in age-hardenable 6xxx series Al-Mg-Si alloy promising as automotive body panels in order to develop favorable textures for the deep drawability after solution treatment. Symmetric cold rolling at high reduction and subsequent asymmetric warm rolling at low reduction for AA6022 sheets led to the formation of “TD-rotated β-fiber texture” including moderate {111}<uvw>-oriented components, resulting in noticeable evolution of {111}<110> recrystallization texture during the solution treatment at a high temperature. The results of texture analysis and microstructural observation suggested that the low stored energy after asymmetric warm rolling, the high fraction of high angle boundaries with neighboring deformed matrices and the approximate 40° <111> orientation relationship with deformed matrices would strongly affect the evolution of {111}<110> recrystallization texture.

Normalizing Annealing

The 4.2wt.%Si non-oriented electrical steel thin sheets with the thickness of 0.30mm were produced by the conventional procedure including hot rolling, cold rolling and annealing. The recrystallization texture was analyzed with emphasis on the effect of normalizing annealing. The results show that the  fiber with peak at {111} is weaker and η ﬁber is stronger in the sheets with normalizing annealing than those without normalizing annealing, either under the cold rolled reduction of 77% or 86%. Effects of normalizing annealing on the recrystallization texture can be explained in terms of the characteristic of the shear bands formed during cold rolling process.
