Abstract

Abstract: Grain boundary characteristics of non-abnormal grown Goss grains of Hi-B steel during secondary recrystallization annealing was studied by using interruption method combined with EBSD technique.The results show that the grain size of non-abnormal grown Goss oriented grains is not significantly different from that of matrix grains and adjacent grains.At the same time,the proportion of HE and CSL grain boundaries around the non-abnormal grown Goss grains has no significant difference with those of abnormal grown Goss grains.During the secondary recrystallization annealing,the size superiority,HE and CSL grain boundary,and Goss orientation deviation can't guarantee the abnormal growth of Goss oriented grains.With annealing temperature increasing,the Goss oriented grains tend to be closer to the standard Goss grains.

Key words: Hi-B steel, secondary recrystallization, Goss oriented grains, abnormal growth
