Recrystallisation of Ti if steel investigated with electron back-scattering pattern (EBSP)

Abstract

The deformed structure of cold rolled IF steels consists of a large number of a fibre and γ fibre oriented grains and a small number of (110)〈110〉 oriented grains, each with a distinctive grain shape, subgrain structure, hardness and etching appearance. Early nucleation occurs mainly in γ fibre grains and (110)〈110〉 grains. The texture of the early nuclei consists of a γ fibre with a spread towards (221)〈110〉 together with a weak 〈100〉//ND fibre. Numerous nuclei develop within a single deformed grain, α fibre grains are consumed only after 70% of the materials is recrystallised.
