WebAug 1, 2003 · The design principle involves creating a high density of interfaces in the transformed products by heat treatment. A nanostructure has been achieved in large … WebThe most potential benefit of bainitic steels is found in the lightweight design of car bodies. The chemical composition, productions process and the austenite state control the properties of those steels. To reach the target of the correct component design it is important to focus on transformation kinetics.
WebMar 18, 2014 · The concepts of phase transformation theory can be exploited to design nanostructured steels that transform to bainite at temperatures as low as 150°C. The microstructure obtained is so refined that it is possible to achieve strength in excess of 2.5 GPa in a material that has considerable toughness (40 MPam1/2). Such a combination … WebOne of the most interesting advances in this area has been the development of bainitic steels, which have been almost dormant since the mid-20th century. ... the concept of employing steel microstructures containing carbon-enriched retained austenite, has been developed further by combining both alloying and novel heat treatment procedures to ...
