Assessing the scale contributing factors of three carbide-free bainitic steels: A complementary theoretical and experimental approach

Materials & Design, 2021
The bainitic ferrite plate thickness is the main parameter that controls the strength of this type of microstructures. Such thickness has been proved to mainly depend on the austenite yield strength, the driving force for the transformation and the ...
