Anisotropy Parameters

The plastic anisotropy parameters (R coefficient and height of ears of the drawn cup) have been calculated from ultrasonic orientation distribution function (ODF) coefficients on the basis of Taylor theory for low carbon steel and aluminium alloy sheets. The ODF coefficients were defined by Sayers method and using the iterative procedure on the basis of measurement of bulk longitudinal and shear wave time delays.

Strain Paths

A low carbon steel (0.07-wt % carbon) sheet metal was deformed in five different strain paths, from equi-biaxial tension to plane strain to near uniaxial tension, by in-plane stretching. Textural developments were characterized by X-ray Orientation Distribution Function (ODFs) and the same were simulated using different Taylor type deformation texture models. A strong difference in bulk texture developments was observed at respective strain paths. The textural differences largely explain the changes observed in normal anisotropy values obtained by mechanical testing. The new deformation texture simulation model, Lamel, was quite successful in predicting quantitatively such textural differences. Microscopically, the significant features of the substructures were “strain localizations”—first generation dense dislocation walls (DDWs) and micro bands (MBs). Both in-grain rotations and estimated stored energies did depend on the relative appearance of such strain localizations. These, on the other hand, were distinctly related to the textural softening or dM/dε, where M and ε are the Taylor factor and true strain, respectively.

A method for obtaining volume fractions in regions about ideal texture components of cubic materials by integration of the orientation distribution function is described. Illustrative examples of the application of the method are given for the primary-recrystallized textures of a 3.15% Si-Fe alloy and several low-carbon steels.

Angle Of Rotation

The development of the rolling texture of a low carbon steel was investigated by neutron diffraction calculating three-dimensional orientation distribution functions. The textures consist of two limited fibre axis components A and B centered about (1¯1¯1)[1¯21]+5∘ and (001)[1¯10] respectively with an angle of rotation of about 70∘. For rolling degrees larger than 50% the intensity of the fibre axis component A is being modulated so as to favour the orientation (1¯1¯2)[1¯10]. The texture may be considered as inverse to the low concentration brass texture in the sense of interchanging rolling and normal directions. It may be understood in terms of {110}〈111〉—glide and {112}〈111〉—twinning.

Rolling Mode

Cube texture ({001}<100>) influences extensively the plastic anisotropy and physical properties of materials. Researches on cube texture have been concentrated in f.c.c structured metals only since the scarce observation of the texture in b.c.c. metals. In the present work, the cube texture was found to be developed in low-carbon steel under the biaxial rolling mode (ND and TD rolling alternatively). Cube texture and {112}-{111}<110> partially concentrated a-fiber texture were observed in biaxially rolled samples instead of the typical a-fiber and g-fiber texture formed in the normal flat-rolling. At 923K rolling where recrystallization occurred, highly developed {001}<110> recrystallization texture with some g-fiber texture was observed in the flat rolled sample. In contrast a quite intensified cube texture and {hkl}<110> texture were observed in the biaxially rolled sample. EBSD measurement showed the fraction of grains belonging to the two orientations was 0.35 and 0.55, respectively. Elongated along RD, grains in cube texture showed both the near-equiaxial and diagonally elongated shapes when observed from RD in the 923K rolled samples. Those grains containing lighter plastic strain had an average grain size (~1.5µm) which was 2 times larger than the grains in the RD//<110> texture. Meanwhile, the cube oriented grains were characteristic of only low-angle grain boundaries (<15o), but showed a specific misorientation (S17b, <110> 86.6o) with the grains in the RD//<110> texture. Besides rolling deformation produced cube oriented grains, preferential growth of cube oriented recrystallization nuclei, and the transformation of the {001}<110> recrystallization grains were considered to cause the development of cube texture during the 923K biaxial rolling.
