Improving Strength-Ductility via Short Austenitization in a Low-Carbon Carbide-Free Bainitic Steel
Crystals, 2022 The strength and ductility of low-carbon carbide-free bainitic (CFB) automotive steel are not good enough. In this study, a short austenitization (SA) process in conjunction with isothermal bainitic transformation was adopted to refine the bainitic ...

Experimental evidence for non-cubic bainitic ferrite [PDF]
Scripta Materialia, 2013 The first evidence is provided for the existence of a tetragonal or slightly orthorhombic unit cell of bainitic ferrite. It supports the hypothesis that the excess carbon that persists in the ferrite, which is in contact with austenite, is a consequence of an increased solubility due to the change in symmetry from the conventional cubic unit cell.

Crystals, 2023 The addition of high-content alloying elements and the unbefitting process make carbide-free bainite steel difficult in industrial production. Thus, we adopted a dynamic continuous cooling process for developing the high-strength cold-rolled low-alloy ...

Influence of boron content on the fracture toughness and fatigue crack propagation kinetics of bainitic steels [PDF]
, 2016 The relatively good combination of high strength and ductility makes bainitic steels a candidate to replace many other steels in industrial applications. However, in service, ductility and strength are not up to standard requirements.
