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.

The impact of hydrogen on the ductility loss of bainitic Fe–C alloys [PDF]
, 2016 The influence of hydrogen on the mechanical properties of generic lab-cast Fe-C bainitic alloys is studied by tensile tests on notched samples. The bainitic microstructure is induced in a 0.2% C and 0.4% C Fe-C alloy by an appropriate heat treatment. The

Variant Pairing of Lath Bainite and Martensite in an Ultra-High-Strength Steel
Metals, 2022 The mixed structure of lath bainite and martensite was obtained by isothermal transformation tests at 698 K, 673 K and 623 K in ultra-high-strength steel. The interweaving mode of lath bainite and martensite was revealed by colored metallography and band

Current Opinion in Solid State and Materials Science, 2004 Steel with an ultimate tensile strength of 2500 MPa, a hardness at 600-670 HV and toughness in excess of 30-40 MPa m1/2 is the result of exciting new developments with bainite. The simple process route involved avoids rapid cooling so that residual stresses can in principle be avoided even in large pieces.
