Carbide-free Bainite: Compromise between Rate of Transformation and Properties

Sangeeta Khare, Kyooyoung Lee and H. K. D. H. Bhadeshia


By identifying the relationship between the time required to obtain bainite and parameters such as the transformation temperature and carbon concentration, it has been possible to institute a design procedure which led to the desired mechanical properties and transformation characteristics. The work has also identified difficulties in the calculation of tensile elongation on the basis of a percolation model which suggests that fracture occurs when the fraction of austenite drops below the percolation threshold in the microstructure.
