Processing and Evaluation of Ferritic-Bainitic Multi-phase Steel
Journal of Petroleum and Mining Engineering, 2017 Production of bainite-ferrite multi-phase steels on industrial CSP scale provides approach to improve mechanical properties along with large cost reduction opportunity. In terms of hot-rolling conditions, chemical composition, and microstructure; characterizing ferritic-bainitic steels and their difference from ferritic-pearlitic steels regarding ...

Critical assessment 20: On carbon excess in bainitic ferrite [PDF]
Materials Science and Technology, 2016 For several decades, the question of carbon supersaturation in bainitic ferrite has attracted the attention of physical metallurgists. Originally, this was associated with excess carbon due to the displacive nature of phase transformation and its subsequent trapping at defects in bainitic ferrite.

Formation Temperature of Bainitic Ferrite in Si-Containing Steels
Materials Transactions, JIM, 1991 A metallographic study of isothermal-transformation products formed at various temperatures was made in 2%Si-1%Mn-0.34%C and 2%Si-1%Mn-0.59%C steels with particular emphasis on the formation mechanism of bainitic ferrite. In the 0.34%C steel, the austenite first decomposes into ferrite and then into pearlite in the later stage of transformation at 973 ...

Mechanism of the Transition from Bainite to Acicular Ferrite
Materials Transactions, JIM, 1991 The factors controlling the transition from a microstructure consisting of austenite grain boundary nucleated sheaves of bainite, to one containing intragranularly nucleated plates of acicular ferrite are explored. The work confirms that in weld metals containing inclusions, the transition from bainite to acicular ferrite can be stimulated of the prior
