Abstract

The deep drawability of ferritic steels can be improved by increasing the r-value, which is closely related to the {111} recrystallization texture. Control of the {111} recrystallization texture in ferritic steel has been extensively studied as the means of improving the deep drawability of the steel sheet. However, no published research has compared the relationship between the r-value and {111} recrystallization texture in mild steels and ferritic stainless steels. The aim of the present research is to clarify the effect of chromium on the relationship between the {111} recrystallization texture and r-value in order to improve the deep drawability of ferritic stainless steels. The following results were obtained through the study using body-centered cubic steels with various chromium content: (1) Ferritic stainless steels show higher r-values than mild steels with the same level of {111} recrystallization texture. (2) Chromium addition is advantageous for realizing higher r-values in ferritic steel. The authors propose that some slip systems in ferritic steels are constrained by chromium atoms, which results in higher r-values in ferritic steels.
