Abstract: Rapid water quenching experiments were first carried out according to differential
scanning calorimetry results, and then the microstructure and phase composition of such water
quenching Cu-8·33Ni-1·67Si (wt-%) samples were investigated. Subsequently, calculation on the
competition nucleation of the primary phase was also carried out. Based on the experimental
and calculational results, the phase transformation behaviour of Cu-8·33Ni-1·67Si melts during
the cooling process was discussed, and the results can be summarised as follows. First, the α-Cu
phase formed as a primary phase due to the shorter incubation time and higher time dependent
nucleation rate. Subsequently, a eutectic reaction occurred in the interdendritic residual liquid
phase of the primary α-Cu grains, and its product was α-CuzNi3Si. The third and fourth phase
transformation could be described to the precipitation of the δ-Ni 2Si phase in the region close to
the grain boundary phase and the internal of the primary α-Cu grains respectively. © 2013
