Abstract

Abstract: A systematic and detailed characterization of FeTiPtype precipitate， as a function of annealing temperature， was studied for a batchannealed Padded interstitial free high strength steel (IFHS). The results showed that a small number of FeTiP is observed at 650 ℃ and it increases dramatically with the increase of annealing temperature. FeTiP distributes within grains and at grain boundaries， but the size of intragranular FeTiP is found to be significantly smaller than that at grain boundary. FeTiP is totally dissolved and can not be detected at 800 ℃. The absence of FeTiP eliminates its inhibition effect on recrystallization and a high intensity {111} recrystallization texture is obtained， which improves the formability of IFHS. FeTiP is orthorhombic structure， and the enrichment of Nb in FeTiP precipitates does not alter the crystal structure of FeTiP.

Key words: interstitial free high strength steel, annealing temperature, FeTiP, crystal structure, texture
