Microstructure Study of Undercooled Hypereutectic Cu₉₅Cr₅ Alloys

Abstract:

Microstructure of Cr-rich phase in undercooled hypereutectic Cu₉₅Cr₅ alloys was studied by using arc melting, electromagntic levitation melting and splat quenching. The results showed that the alloys generally have a microstructure consisting of a fine Cr-rich dendrites in a Cu-rich matrix. Even there existed strong electromagnetic stirring during solidification process, the nonhomogeneous Cr-rich dendrites were observed in electromagnetic levitation melted alloys. However, fine homogenous primary Cr-rich particles or equiaxed Cr-rich grains distributed in the Cu-rich matrix in splat quenched alloys.
