Orientation Relationship during Partial α-γ-Phase Transformation in Microalloyed Steels

Article Preview

Abstract:

The ferrite to austenite phase transformation in microalloyed steel was studied, with a special focus on the orientation relationship between prior ferrite and subsequent austenite. Also the role of growth selection and preferred nucleation was investigated in this context. Their effects were examined at partial phase transformation.
