Comments on “Bainite formation kinetics in high carbon alloyed steel”
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 کاملElectron backscattering diffraction study of coalesced bainite in high strength steel weld metals
Coalesced bainite is a coarse constituent recently found to develop along with the classical martensite, lower and upper bainite in steel weld metals. Its crystallography has been characterised using electron backscattering diffraction in combination with field emission gun scanning electron microscopy. It is confirmed that coalesced bainite grains are crystallographically homogeneous but do co...
متن کاملPrediction of Bainite Intervention in Ferrite-Pearlite Forging Steel I. Modeling
The successive ferrite (α) + pearlite (P) transformations from austenite (γ) have been modeled to predict the intervention of bainite in as-forged medium-carbon manganese steels. The kinetics of the diffusional transformations were calculated based on the classical nucleation-growth theory coupled with the CALPHAD multi-component thermodynamics. The description of growth rate of proeutectoid-α ...
متن کاملIdentification of Retained Austenite, Ferrite, Bainite and Martensite in the Microstructure of TRIP Steel
Transformation induced plasticity (TRIP) steels have a vast application in automotive industry because of theirhigh strength, high ductility and hence excellent energy absorption capacity. These characteristics of TRIPsteels are due to the existence of retained austenite in their microstructures in the ambient temperature, whichtransforms to the martensite phase during deforma...
متن کاملDrawing CCCT Diagrams and Investigation of Deformation Effects on Martensite and Bainite Trabsformations in NiCrMoV Steel
In this study, two CCCT diagrams are drawn to be compared with a CCT diagram. The CCCT diagrams represent continuous cooling transformations in stress assisted state. The increased Md and Bd temperatures of CCCT diagrams were also compared with those of the CCT diagrams and the cause was investigated from both thermodynamic and metallurgical viewpoints. Thermodynamic examinations revealed that ...
