Method for preparing beryllium-vanadium alloy by adopting spark plasma sintering technique

The invention belongs to a preparation method of beryllium-vanadium alloy and in particular relates to a method for preparing beryllium-vanadium alloy by adopting a spark plasma sintering technique. The method comprises the following steps: firstly, material proportioning; secondly, sintering; and thirdly, polishing. The method for preparing the beryllium-vanadium alloy by adopting the spark plasma sintering technique has the advantages that firstly, sintering time is greatly shortened so that energy source is greatly saved; secondly, due to activation of plasma, low-temperature sintering can be realized, and since sintering temperature is lower than melting points of beryllium and vanadium, growth of crystalline grains is inhibited and the alloy performance is essentially improved; and thirdly, sintering is carried out in a closed environment and therefore beryllium protection pressure is reduced; the prepared beryllium-vanadium alloy can be proved by adopting test means such as X ray diffraction and an electron probe; meanwhile, a scanning electron microscope finds that development of the crystalline grains of surface sintering bodies is comparatively complete, shape is regular, size is consistent, arrangement is tight, overall structure is compact, and distribution is uniform.
