Abstract：Bcontaining((40～60)×106,mass fraction) and Bfree 08Al hot strips produced by CSP process were used for experiment. The hot strips were coiled at different temperatures and then cold rolled with different reduction rate. After recrystallization annealing, the formability(rvalue and nvalue) and mechanical properties (YS，TS and A) were measured by tensile tests, in addition, two kinds of annealed sheets (coiling temperature 620 ℃;75% reduction) were analyzed by Xray diffraction(ODF) and electron backscattered diffraction (EBSD). The results showed that coiling temperature and total coldrolling reduction rate have remarkable influence on the formability and mechanical properties of Bcontaining and Bfree 08A1 steels after recrystallization annealing.ODF EBSD tests showed that the fraction of γfiber texture in Bcontaining steel is lower than that in Bfree steel, nevertheless, the rotating cubic texture ({001} <110>) and Goss texture ({011} <100>) are much more than that in Bfree steel.
