“…1(b)). Further, the dynamic strain aging also results in the preferential retardation of slip on the {110}<111> system 12) resulting in the strengthening of the α fiber components at the expense of the γ fiber components 13) which is clearly evidenced in the texture of ferrite in A0 specimen (Fig. 3).…”

The evolution of microstructure and texture during isothermal annealing of a heavily warm-rolled duplex steel (DSS) was studied. For this purpose a DSS steel was hot rolled, homogenized at 1 448 K and subsequently warm-rolled to 90% reduction in thickness at 698 K and 898 K. This was followed by isothermal annealing at 1 448 K for different time intervals up to 7 200 seconds. Lamellar microstructure with alternate arrangement of deformed ferrite and austenite bands was observed in the as warm-rolled condition.The ferrite in DSS warm-rolled at 698 K showed much stronger α-fiber (Rolling direction (RD)//<110>) than γ -fiber (Normal direction (ND)//<111>) as compared to the ferrite in DSS warm-rolled at 898 K. The austenite in warm-rolled DSS showed a predominantly pure metal (or copper type) texture. Upon annealing the lamellar morphology of the as warm-rolled structure transformed into a bamboo type morphology for short annealing time but finally broke down with increasing isothermal annealing time due to mutual interpenetration of the two phases. Retention of deformation texture components and presence of annealing twins in austenite indicated discontinuous recrystallization. Despite differences of texture in the as warm-rolled condition the ferrite in annealed DSS showed much stronger α-fiber as compared to γ -fiber due to strong recovery behavior of ferrite during annealing. The texture evolution in the two phases was not affected by the presence of the other phase while grain growth was significantly restricted due to the presence of the other phase.

The addition of microalloying elements such as Ti and Nb to increase the strength of deep drawing quality steels for automotive sheet products might affect the microstructure formed during the annealing after warm rolling in several ways. Firstly, the precipitates can exert a Zener's pinning on growing recrystallized grain, which leads to a sluggish recrystallization kinetics. Secondly, the amount of microalloying elements control the amount of C, N, S, and P in solid solution, which indirectly affects the recrystallization texture obtained after annealing. In this sense, the work carried out with three different interstitial free (IF) and interstitial free high-strength (IFHS) steel grades allows us to conclude that the increase of microalloying additions delays recrystallization kinetics. Moreover, the abrupt texture change observed between as-rolled and annealed material indicates that the nucleation mechanism for recrystallization is more related to classical nucleation at deformed grain boundaries than subgrain rotation (continuous nucleation).
