It is demonstrated that bainite can be obtained by isothermal transformation at a temperature which is so low that the calculated diffusion distance of an iron atom, over the time scale of the experiment, is many orders of magnitude less than an ...

Modeling of bainitic phase transformation [PDF]
AbstractIn this work, we present a macroscopic material model for simulation of austenite to bainite and of austenite to martensite transformations accompanied by transformation‐induced plasticity (TRIP), which is an important phenomenon in metal forming processes.

Modeling Bainitic Transformations during Press Hardening [PDF]
We revisit recent findings on experimental and modeling investigations of bainitic transformations under the influence of external stresses and pre-strain during the press hardening process. Experimentally, the transformation kinetics in 22MnB5 under various tensile stresses are studied both on the macroscopic and microstructural level. In the bainitic

Effect of Carbon Content on Bainite Transformation Kinetics and Microstructure of 4140/4150 Steels [PDF]
4140 steel and 4150 steel are different only in their carbon content. A comparison between the kinetics and microstructure of the bainite transformation of both steels has been carried out under a wide range of isothermal temperatures, in which four ...
