Zr46Cu46Al8, known for its good glass forming ability (GFA), exhibits a complex crystallization pathway. Initially, a transition region emerges, eventually evolving into the thermodynamically stable crystalline phase of Cu10Zr7, facilitated by continuous chemical redistribution at the late stage of annealing. In contrast, Zr56Cu36Al8, a poor glass former, crystallizes directly into the thermodynamically stable crystalline phase of CuZr2 in a single step, with no observed chemical redistribution. Overall, the results suggest that continuous chemical redistribution following structural ordering may contribute to stabilizing the amorphous state and improving the thermal stability of BMGs.
