Comparative study of precipitation behavior and texture formation in continuously annealed Ti and Ti + Nb added interstitial-free high-strength steels

Two interstitial-free high-strength (IFHS) steels processed by continuous annealing, with and without Nb addition, have been studied. No major differences in precipitation behavior or texture formation in the two steels were observed. Nb addition does not improve the formability as such, but it appears to coarsen the carbide precipitates and reduces the volume fraction of the {1 1 1}〈1 1 0〉 texture component in the γ fiber.
