In the present work,the microstructure,texture,and mechanical properties of a cold-rolled Ti-IF steel, after annealing at different heating rates,have been investigated.The results reveal that the mean grain size is gradually refined from19.2 to 16.3μm as the heating rate increases from4 to50℃/s,but refined only slightly at heating rates of over 50 ℃/s.The recrystallization microstructure has a strong texture,which is a result of the sharpening of the favorable{111}//ND(normal direction)texture components orγ-fiber.With increasing heating rates,the peak value of f(g)ofγ-fiber decreases from17 to9.The yield and tensile strengths increase gradually as the heating rate increases from4 to 50℃/s,but remain almost unchanged at heating rates of more than 50℃/s. The total elongation and uniform elongation increase gradually as the heating rate increases from4to100℃/s,but decreases slowly for heating rates higher than100℃/s.As the heating rate increases from4to100℃/s,the plastic strain ratio of the steel decreases from2.8to2.2;however,it increases to2.9for heating rates above100℃/s.The strain hardening exponent remains unchanged at 0.27in all annealing cycles.
