Grain Boundary Distribution Evolution of 00Cr12Ti FSS during Annealing

Abstract

The texture and grain boundary of 00Cr12Ti FSS have a close correlation with properties and should be controlled to optimize the performance of steel sheets. In this paper, the macrotexture evolution during recrystallization annealing was investigated by XRD, the microtexture and grain boundary distribution evolution during recrystallization annealing were investigated by EBSD. The results showed that the γ fiber texture were mainly generated by replacing α fiber texture in recrystallization process. But with the holding time extending, γ fiber texture transferred to other texture after the holding time got to a certain degree. The major CSLs in 00Cr12Ti FSS after recrystallization are Σ3 and the frequency of Σ3 climb up and then decline with the holding time extending. Σ11 plays an important role in the process of recrystallized γ fiber texture formation.
