Abstract
Hastelloy C-276 was subjected to low strain deformation and then annealed at 1100 °C for different time. The â3 and â9 boundary percentages and grain boundary plane distributions were characterized by electron back-scatter diffraction (EBSD) and a five-parameter analysis method. The results show that the â3 boundary evolves towards a more exact coincident-site lattice (CSL) misorientation and the â3 boundary plane is closer to low surface energy plane {111} with the increasing of annealing time. This is consistent with fine tuning mechanism. While the population of incoherent â3 boundary is increasing, the proportion of â9 boundary with larger deviations increase, too. And the distributions of grain boundary density planes for â9 boundary are more intensive on the whole [110] zone.
