摘要：
The microstructures and solidification processes of CuCr25 alloys are studied under different cooling rates in the present paper. With increasing of the cooling rate, the microstructures of CuCr25 alloys become finer and finer. When the cooling rate is up to 107K/s, nano-microstructures can be obtained. When the cooling rate is less than or equal 103K/s, the solidification process of CuCr25 alloys belongs to a general solidification process; if the cooling rate is >104K/s, it belongs to the liquid phase separation process. In rapid solidification process, there is no new phase formed in CuCr25 alloys, but the solubility of Cu in Cr-rich phase and Cr in Cu-rich phase will increase.
