U-10Zr porous metal fuel forming method

The invention belongs to the technical field of nuclear fuel element manufacturing, and particularly relates to a U-10Zr porous metal fuel forming method. The alloy is prepared according to the weight ratio of 1: 1, and stirring alloy smelting is conducted; smelting in a vacuum induction furnace, preserving heat, stirring for multiple times, and then pouring into an ingot; putting the cast ingot into a vacuum annealing furnace, heating, raising the temperature, and preserving heat; after the cast ingot is extruded, the alloy bar is cut into slices; cleaning the alloy sheet by nitric acid-distilled water-absolute ethyl alcohol, and transferring the alloy sheet into a hydrogenation and dehydrogenation furnace; transferring the hydrogenated and dehydrogenated powder into a ball mill in an argon atmosphere for grinding, sieving, and carrying out compression molding; and carrying out vacuum sintering and heat preservation on the molded green body. The forming process is easy to operate, the mold is free of lubrica
