Prediction of the glass-forming ability of Fe-B binary alloys based on a continuum-field-multi-phase-field model

摘要

In this paper, a continuum-field-multi-phase-field (CF-MPF) model was adopted for simulation of the glass transformation and the competition between amorphous phase and crystalline phase during the rapid solidification process in Fe-B binary alloys. The transition process of liquid phase? amorphous phase + crystalline phase was investigated. The influence of different cooling rates (dT/dt) on the competition between amorphous phase and crystalline phase were analyzed. It was found that the values of critical cooling rate (R-c) estimated by the CF-MPF model were in good agreement with the reported experimental values, which verified the feasibility of the glass prediction and experimental guidance by the CF-MPF model.
