MICROSTRUCTURE OF GRANULAR BAINITE
Le Journal de Physique Colloques, 1988 A 2.25Cr - 1Mo - 0.1C welded steel having a microstructure described as "granular bainite" has been investigated using optical microscopy, electron microscopy and atom probe field ion microscopy. Granular bainite was found to consist of bainitic ferrite and retained austenite, but no cementite.
