“…It is not very meaningful to make a quantitative comparison of the r-value between type 329J4L and ferritic single-phase Texture and Planar Anisotropy of r-Value in Duplex Stainless Steel Sheetstainless steel sheets with different textures, but the improvement of the average r-value with the increase in cold-rolling reduction is qualitatively similar to that in the case of ferritic stainless steel sheets. However, the magnitude of anisotropy is large in comparison with the ferritic and austenitic steel sheets, [27][28][29] and there is a characteristic that the r-values in the vicinity of the diagonal direction are remarkably high for type 329J4L DSS sheet. Figure 5 shows the microstructures (TD plane) of the final annealed sheets.…”

The effect of cold-rolling reduction on texture and planar anisotropy of the r-value was investigated in type 329J4L duplex stainless steel (DSS) sheet, which has a two-phase ferrite () and austenite () microstructure. In addition, the possibility of predicting the planar anisotropy of the r-value on the basis of the Taylor theory was investigated in consideration of the texture gradient through the thickness. An increase in coldrolling reduction resulted in the improved average r-value and the strong directionality with a maximum value at the diagonal direction. The phase had an extremely strong bcc -fiber texture and the phase had -and fcc -fiber textures. The texture gradient in the thickness direction was more remarkable in the phase than in the phase. The r-values calculated from the overall texture of the phase using the relaxed constraints model with two relaxed shear strain constraints e 13 , e 23 and a CRSS ratio of 1.1 for {112} and f011gh111i glide systems were in quite good agreement with the experimental r-values. This suggested that slip deformation in the matrix was dominant for type 329J4L DSS sheet. However, the difference between the experimental and calculated results was remarkable in the vicinity of the diagonal direction.

“…1,[9][10][11][12] Yazawa et al 12) showed that the relation between {111} intensity and average r-value was dependent on chromium content of the steel, and that ferritic stainless steel sheets had a higher r-value than mild steel with the same level of {111} intensity. However, the effects of factors other than {111} recrystallization texture on the r-value remained unclear.…”

Effect of Texture on r-value of Ferritic Stainless Steel Sheets

The effects of cold rolling texture on the formation of recrystallization texture and the relationship between recrystallization texture and r-value were investigated for sheets of titanium-stabilized extra-high purity Type 436L and Type 409L ferritic stainless steels. The recrystallization texture and average r-value were affected by the cold rolling texture. Annealed sheets with a sharp γ-fiber texture and very high average r-values were obtained from cold-rolled sheets with a strong γ-fiber texture (Type A). On the other hand, the {h,1,1}<1/h,1,2> fiber texture developed from cold-rolled sheets with a strong α-fiber texture (Type C). In terms of the relationship between {111} intensity and the average r-value, chromium content had less effect than the cold rolling texture. The planar anisotropies of r-values and the average r-values of Type 436L and 409L sheets with Type A cold rolling textures agreed well with those calculated from the textures in the center layers by using the relaxed-constraints model and the CRSS ratio τc{211}/τc{110} of 1.1. On the other hand, for the sheets with Type C cold rolling textures and a marked texture gradient, it was necessary to consider the texture gradient in the thickness direction. The texture inhomogeneity by the orientations other than {111} texture affected the relationship between {111} intensity and average rvalue.

The limits for carbon and nitrogen, (Table 51.7) for this alloy are a result of extensive research on this composition at the laboratories of the Climax Molybdenum Company [84][85][86]. To maintain the concentrations of carbon and nitrogen as shown in Table 51.7, the alloy must be made by the AOD or VOD process.…”
