Effects of Ti and Nb Stabilization on the Recrystallization and the Pitting Potential in Fe-21%Cr Ferritic Stainless Steels

Abstract:

Effects of Ti and Nb stabilization on the recrystallization and the pitting potential in Fe-21%Cr ferritic stainless steels were studied by using optical microscopy, scanning electron microscopy, transmission electron microscopy and polarization curve measurement. The results show that both Ti and Nb, either in solution or as precipitates, retard the recrystallization and enhance the recrystallization temperature. Substitution of Nb for Ti in Fe-21%Cr ferritic stainless steels increases the recrystallization temperature by 30 to 50°C. Nb and Ti stabilized ferritic steels present higher pitting potential than Ti stabilized steels.
