Abstract

Abstract

The solidification structure and inclusions of high-purity ferritic stainless steel stabilized with Ti or Nb were investigated by the optical microscopy (OM) and scanning electron microscopy (SEM). The results showed that Ti could increase the isometric crystal ratio and Nb could refine crystal size in the high-purity ferritic stainless steel. The composition and status of inclusions were all significantly different in the high-purity ferritic stainless steel stabilized with Ti and Nb,respectively.
