Abstract

Effects of annealing temperature and holding time on the oxide scale of high strength IF steel were studied by scanning electron microscopy (SEM) and glow discharge optical emission spectroscopy (GDOES). The results show that the surface of oxide scale of high strength IF steel after annealing was mainly composed of Mn and B oxides. P oxides were enriched in the surface of oxide scale, Al oxides were mainly formed in the inside of oxides scale. With the increase of annealing temperature and holding time, Mn oxide increased but B oxide decreased in the surface of oxide scale, the enrichment of P increased, Al oxide generated in both the steel substrate and the oxide scale.
- high strength IF steel,
- annealing temperature,
- holding time,
- oxide scale
