Bainite transformation under the effect of large stress in a carbide-free bainite steel
Journal of Materials Research and Technology, 2023 The effects of large stress on bainite transformation and microstructure were investigated by dilatometry, SEM and EBSD. The results show that the effect of large stress on bainite transformation includes two parts: mechanical driving force and prior ...

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2009 An alloy system based on iron is described in which it has been possible to create a high density of interfaces by heat treatment alone. The resulting structure consists of a mixture of slender platelets of bainitic ferrite, just 20–40 nm in thickness, embedded in a matrix of carbon-enriched austenite.

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.

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
