The application discloses a high-softening-point rare earth copper tungsten alloy and a preparation method thereof, and relates to the technical field of alloy materials.The method is characterized by the following steps: doping cerium oxide and zirconium into tungsten phases and copper phases respectively, mixing, and sintering through a sectional hot isostatic pressing process, so that the problems of element segregation caused by the difference in specific gravity are effectively improved, the dispersibility of each phase is obviously improved, the pinning effect of the rare earth oxide on the tungsten phase and the diffusion-promoting effect of the zirconium on the copper phase boundary are enhanced, the tungsten grain growth is effectively inhibited, the interface bonding strength of the copper phase and the tungsten phase is improved, the softening point temperature of the copper tungsten alloy is obviously improved, the segregation problem of the copper phase in the densification process is obviously improved, the copper grains are refined, and the densification of the copper phase is obviously improved.The preparation method has the advantages of simple process, stable and controllable product performance, and is suitable for large-scale production of the high-softening-point rare earth copper tungsten alloy.
