Reconstruction of austenite grain boundaries in bainitic reactor pressure vessel steels by EBSD

Chekhonin, P.; Bergner, F.

Abstract

The reconstruction of austenite grain boundaries in bainitic reactor pressure vessel (RPV) steels by means of electron backscatter diffraction (EBSD) was done on two examples. In the case of VVER-440 RPV steel the reconstruction works very well, while in JFL RPV steel the reconstruction is faulty due to the accented presence of low angle boundaries.
