摘要：

The solidification behavior of undercooled Cu98Cr2 alloys was investigated under different rapid solidification methods. The results shown that whole lamellar (alpha+beta) eutectics appeared in melt spun alloys for the sample undercooled into the coupled zone. The microstructure of arc melted Cu98Cr2 alloys consisted of primary beta(Cr) particles distributes on alpha(Cu) matrix and (alpha+beta) eutectics set in cellular alpha (Cu) phase. However, due to the different thickness and different solidification rate, the microstructure of splat quenched Cu98Cr2 alloys shown that only cellular supersaturated a solid solution occurred for thin flake and primary beta(Cr) particles and (alpha+beta) eutectics occurred for thicker flakes.
