Description

technical field

[0001] The invention belongs to the technical field of composite material preparation, and in particular relates to a Cu-Fe composite double-melt mixed casting equipment and process. Background technique

[0002] The Cu-Fe composite material combines the high electrical conductivity and thermal conductivity of Cu with the soft magnetic properties, high strength and stiffness of Fe, and has unique electromagnetic shielding properties. It is widely used in pulsed strong magnetic field systems, particle acceleration electromagnetic launchers, High-energy synchrotron radiation light sources and other high-tech fields.

[0003] During the solidification process of Cu-Fe composites, two kinds of liquid phase regions will be formed, namely the Cu-rich region (L 1 ) and Fe-rich region (L 2 ). Due to the different composition of the two liquid phases, the Stokes motion caused by the density difference leads to macrosegregation under the action of the gravity field,...
