New approach for the bainite start temperature calculation in steels
The bainite start temperature Bs is defined as the highest temperature at which ferrite can transform by a displacive transformation. A common observation is that the bainite start temperature is very sensitive to the chemical composition, indicating that the influence of solutes is more than just thermodynamic. Empirical linear regression models have long been used to calculate the Bs in a lim...
متن کاملBainite formation influenced by large stress
By using an iron alloy that transforms slowly to bainite at a low temperature, it has been possible to study the development of the upper bainite under the influence of exceptionally large stresses, which are nevertheless below the yield strength of the parent austenite. It is found that a uniaxial stress whose magnitude is below the elastic limit, strongly favours the growth of compliant varia...

We examine here the physical aspects and input parameters of a recently published model on the overall transformation kinetics of the bainite reaction in steels.
متن کاملDevelopment of Hard Bainite
The T0 temperature in steel is defined as that at which ferrite and austenite of the same chemical composition have identical free energy. The T0 temperature is that below which it is possible for austenite to transform to ferrite of the same chemical composition after allowing for the strain energy due to the displacements associated with the transformation. Bainite is expected below the T0 te...
متن کاملDuctility of Nanostructured Bainite
Nanostructured bainite is a novel ultra-high-strength steel-concept under intensive current research, in which the optimization of its mechanical properties can only come from a clear understanding of the parameters that control its ductility. This work reviews first the nature of this composite-like material as a product of heat treatment conditions. Subsequently, the premises of ductility beh...
