Phase field simulation of liquid-solid-eutectoid multiple phase transformations of a Fe-C binary alloy

China Foundry, 2020
A new continuous multi-phase transformation field model was established for liquid-solid-eutectoid transformation. Taking Fe-C alloy as an example, the model was used to simulate the evolution of the micromorphology of the liquid-solid phase transition ...

Alteration of Phase Transformation Behavior and Prior Austenite Grain Structure Due to Elevated Tramp Element Concentrations in a Hypoeutectoid Steel

steel research international, EarlyView.
The phase transformation behavior of a hypoeutectoid steel is studied in comparison with alloys containing higher concentrations of tramp elements, simulating high recycling rates. The examination of microstructures reveals that the tramp elements facilitate the formation of displacive phases along with retained austenite.
