摘要：
Quenching studies of CrB-Al, CrB-Al-B and ss-FeB-Al mixtures revealed that all three undergo a topotactic transformation in the presence of Al to form Cr2AlB2, Cr3AlB4, and Fe2AlB2 MAB phases, respectively. The formation mechanism is intercalation for the Cr-based compounds, and reconstructive for the ss-FeB based mixture.
