“…We can thus relate more precisely the formation of ridging with the texture. [14][15][16][17][18][19][20][21][22][23] Equal-channel angular pressing (ECAP) is one severe plastic deformation (SPD) that emerged as a new process for fabricating bulk ultrafine grained (UFG) or nanocrystalline materials. 24) Various metallic materials such as copper and aluminium can be fragmented into an ultrafine grain size after six to eight passes.…”

“…Over this time, different groups have argued for and against various models, most notably those of Chao, [1] Wright, [2] and Takechi. [3] The application of crystal plasticity simulations to large-scale experimental electron backscatter diffraction (EBSD) data [4][5][6] has most recently advanced this debate. Although previous EBSD studies had provided evidence for texture banding in the rolling direction-transverse direction (RD-TD) plane, [7][8][9] recent crystal plasticity calculations have unambiguously identified these texture bands as having a strong tendency for out-of-plane shear as required by the Takechi model for roping.…”

The recent application of crystal plasticity calculations to electron backscatter diffraction (EBSD) data from ferritic stainless steel sheet has confirmed the presence of grain clusters parallel to the rolling direction (RD) with similar deformation tendencies. The results of these simulations provide strong support for the Takechi model of roping. The remaining question that has not yet been adequately addressed is how the deformation tendencies of grains/grain clusters are affected by being embedded within a three-dimensional medium. In this article, the behavior of individual grain orientations when embedded within media of differing crystallographic orientations is explored within the framework of a viscoplastic self-consistent (VPSC) model. It is shown that the tendency for out-of-plane shear exhibited by some grain orientations persists, even when the grains are embedded within a matrix that has very different deformation tendencies. This is further extended to examine the influence of the orientation of grain clusters in relation to the roping phenomenon.

Application of Recrystallization Texture Evolution Model to Type 430 Stainless-Steel Strip Production

The ridging phenomenon of type 430 stainless-steel originates from the texture due to crystal plasticity anisotropy. Thus, to predict the antiridging property, we must continuously analyze the hot-rolling, hot-rolling and annealing, cold-rolling, cold-rolling and annealing textures. However, it has been previously difficult to analyze the recrystallization texture. We thus developed a model to predict the recrystallization texture coupled with the Taylor rolling model. Furthermore, the ridging index was calculated in order to estimate the plasticity in type 430 stainless-steels. The plasticity prediction method was applied to type 430 stainless-steel strips rolled at a low temperature with a high reduction rate in an actual tandem hot strip mill.
