摘 要:<正>Phases of Cu-(0.4%-2.0%)Cr-(0.05%-0.16%)Zr alloys were analyzed in both as cast and deformed state. Solute-rich clusters of Cr,which was supposed to form during aging treatment,were observed in as cast state; along with the morphology character,corresponding preferential orientation of Cr phase in as cast state was also investigated.Precipitates were observed to distribute in the matrix with a bimodal distribution,viz. coarse precipitates with dimension larger than several hundred nanometers and fine precipitates with size of 2- 10 nm.Three types of intermetallics,the common compound of Cu51Zr14,correspondingly infrequent Cu5Zr and rare Cu8Zr3,were characterized in different samples.
