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 کاملSevere tempering of bainite generated at low transformation temperatures
The response of a strong bainitic–steel to tempering at high temperatures is investigated, because a softened state is sometimes necessary during the manufacture of engineering components, prior to the final heat–treatment which hardens the material. Thermodynamic calculations conducted to determine the maximum temperature at which the steel could be annealed without forming austenite were foun...
متن کاملEffect of austenite grain size and bainite morphology on overall kinetics of bainite transformation in steels
The effect of austenite grain size on the evolution of the bainite transformation in steels is not yet certain in spite of many investigations.1–7 Barford and Owen1 reported that the reaction rate was accelerated by decreasing the grain size, because of an increase in the number density of grain boundary nucleation sites. Umemoto et al.2 reported similar results and proposed an equation that de...
متن کاملDesigning low carbon, low temperature bainite
The possibility of producing bainite at low temperatures by suppressing transformation using substitutional solutes has been investigated, as an alternative to using large carbon concentrations to achieve the same purpose. It is found that although transformation temperatures can indeed be suppressed in this way, the difference between the bainite and martensite start temperatures diminishes. T...
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...
