Aging by Precipitation of Nb (C,N) In Extra Low Carbon Content Steel

摘要

Carbonitride precipitation has been studied in a high-niobium acicular-ferrite-type steel. Interphase precipitation occurred only in those samples in which high transformation temperatures led to distinctly polygonal-ferrite microstructures. In this latter case, precipitation occurred during a subsequent aging treatment, with a strong tendency for heterogeneous nucleation on dislocations. (Atomindex citation 14:771222)
