Bainitic ferrite plate thickness evolution in two nanostructured steels

, 2021
Bainitic ferrite plate thickness evolution during isothermal transformation was followed at the same holding temperatures in two nanostructured steels containing (in wt.%) 1C‐2Si and 0.4C‐ 3Si. A dynamic picture of how the bainitic transformation evolves

Analysis of transformation plasticity during bainitic transformation under externally applied stress

, 2019
A computational model is proposed to calculate the transformation strain of bainitic transformation in steel under an external stress. To evaluate the difference of nucleation rates among the bainitic variants within a parent austenite grain, the ...

Effect of ausforming on the anisotropy of low temperature bainitic transformation

, 2019
Ausforming is the process by which austenite is plastically deformed prior to bainitic or martensitic transformation. The advantages of such a process on the kinetics of the bainitic transformations have already been reported, but little is found about ...
