Effects of Carbon and Nitrogen Contents on Recrystallization Behavior in Ti added High Purity 11Cr Stainless Steels

Abstract

The effects of (C+N) contents on the recrystallization behaviors of Ti added high purity ferritic stainless steels were investigated. Recrystallization and grain growth of Ti added ferritic stainless steels retarded as Ti and (C+N) contents increased. It is considered that the retardation of recrystallization and grain growth in Ti added steels became more significant through the increase in the Ti and C contents accompanied by the increase in the amount of Ti(C, N), which pinned dislocations and grain boundaries.
