| Abstract | The solidification behavior and as-cast microstructure in AZ80-Bi magnesium alloy were analysed by OM, SEM, XRD and DSC. Meanwhile, the evolution of the solidification microstructure of AZ80-2%Bi alloy was studied by heating-quenching experiments. The results show that the as-cast microstructure of AZ80-2%Bi consists of primary alpha-Mg matrix, divorced eutectic beta-Mg(17)Al(12) phase and Mg(3)Bi(2) phase. The Mg(3)Bi(2) phase exists in the flake-like and granule-like morphologies. With 2.0%Bi addition, the solidification procedure of AZ80 magnesium alloy is changed. The ternary eutectic transformation L-->alpha-Mg+beta-Mg(17)Al(12)+Mg(3)Bi(2) (at 435 degrees C) takes place during solidification of AZ80-2%Bi alloy instead of the binary eutectic transformation L-->alpha-Mg+beta-Mg(17)Al(12) (at 437 degrees C) in AZ80 alloy. Comparing with AZ80 alloy, the nucleating temperature of primary alpha-Mg in AZ80-2%Bi alloy is decreased from 568.8 degrees C to 562.6 degrees C, and the eutectic temperature is also decreased from 424.2 degrees C to 421.1 degrees C. |
