Preparation method of beryllium-titanium alloy pellets

Abstract

The invention discloses a beryllium-titanium alloy pellet preparation method, and belongs to the technical field of beryllium-titanium alloys, and the method comprises the following steps: placing beryllium sheets and titanium particles in a copper crucible fixed in a smelting furnace, carrying out water cooling, vacuumizing, continuously filling argon into the smelting furnace, adjusting the power by stages, carrying out vacuum smelting on the beryllium sheets and the titanium particles, and then carrying out cooling molding to obtain the beryllium-titanium alloy pellet. A beryllium-titanium alloy ingot is obtained; the beryllium-titanium alloy ingot is sequentially subjected to linear cutting machining and finish machining, and beryllium-titanium alloy cutting materials of different sizes are obtained; and the beryllium-titanium alloy cut material is sequentially subjected to radio frequency plasma spheroidizing treatment, collection and screening, and the beryllium-titanium alloy small balls are obtained. The beryllium-titanium alloy pellet disclosed by the invention is uniform in particle size, low in hollow rate and high in sphericity and compressive strength, and meets the use requirements of neutron multiplication materials.
