Abstract:
The influence of boron on the texture of low carbon deep drawing steel sheets was studied with B-contained and B-free low-carbon hot-rolled and batch-annealed strips produced by CSP(compact strip production) as experimental materials.Texture formation and development of the hot-rolled and batch-annealed strips were analyzed in terms of chemical composition and precipitates by electrolytic chemical phase analysis, internal friction and Raman analysis.The results show that the AlN content of B-free hot-rolled strips is much more than that of B-contained hot-rolled strips, but the latter texture is better than the former.The AlN contents of B-free and B-contained annealed strips are almost equal, however, the texture of B-contained annealed strips is bad.It is indicated that AlN is not only the determinant factor that affects texture development, but B and BN also have some influences.
