Abstract: It will also be shown that for the purpose of quantitative data analysis. the q-value (contraction coefficient) deserves some preference over the commonlyused r-value.

“…10, good quantitative agreements between measured and calculated values were obtained for the planar anisotropies and average r-values predicted by using the RC1323 model with a CRSS ratio τ c{211} /τ c{110} of 1.1 for both Type 436L and Type 409L. It has previously been shown that the RC1323 model is appropriate for sheets of low-carbon steel 21,22,24) and ferritic stainless steel sheets. 27) Our results for Type A show that this calculation method is also suitable for the materials having extremely high r-values.…”

“…23,24) Here, the RC1323 model, i.e., the pancake version in which e13 and e23 (where 1, 2, and 3 are defined as the tensile, width, and thickness directions, respectively) were left free, was used as the RC model, because it was an optimal model for BCC steels in previous studies. 21,22,24,27) In the case of the FC model, only the {110} slip plane was considered, and in the case of the RC1323 model, in addition to the {110} slip plane, the values of the critical resolved shear stress (CRSS) ratio for the {211} and {110} glide planes (τc{211}/τc{110}) were assumed to be 0.9, 1.0, and 1.1 in these calculations. Figure 10 shows the measured and calculated planar anisotropies of the r-value for some recrystallized samples of Type 436L and Type 409L with different cold rolling textures of Types A and C, which have high r-values.…”

“…5, was used in the RC model because it has successfully been used for BCC metals in previous studies. 13,15,22,25) Assuming that the elongation in the tensile direction is d" and that the contractions in the width and thickness directions are qd" and ð1 À qÞd", respectively, the deformation tensor can be defined as follows.…”

“…Predictions of the anisotropy of the rvalue in polycrystalline materials have been made using a crystallite orientation distribution function (ODF) and theoretical treatments based on the Taylor theory. [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] The pole figures required for calculating the ODF are generally obtained from the X-ray diffraction of a plane parallel to the sheet surface. However, it is known that some ferritic stainless steel sheets and some Fe-3% Si steel sheets have inhomogeneous texture in the thickness direction.…”
