MAIN DEVELOPMENTS

Beryllium with ~99,999% of purity was obtained by the method of multiple vacuum distillation. Fine-grained components with grain size lower 5 mkm were produced from beryllium of high purity by the method of hot deformation. Mechanisms of deformation of cast and powder beryllium under different condition of testing are studied.

Technology of production of fine beryllium foils is also developed in State enterprise  “Science-technology center “Beryllium” of National academy of sciences of Ukraine; serial production of vacuum-tight foil of beryllium with thickness 8 mkm was developed.

Technology of production of long-sized wire of pure beryllium is developed (r=0,055 mkOm/cm at 77 K) suitable for the use in hyper conducting systems (j~104 A/cm²). Experimental cryogenic transformer is fabricated with winding of Be wire.

In the Field of Powder Metallurgy of Beryllium:

Technology is developed, equipment is produced and industrial production of beryllium powders and aluminum-beryllium alloys with sphere shape of particles by the method of melt atomization is developed.

-         Technology of deformation treatment of atomized powders of such alloys is developed;

-         Technology of hot isothermal compacting (HIC) of atomized Be powders for production of components of complex shape with isotropy properties is developed;

-       Technology of plates and rods of metal hafnium is developed; these pieces meet the demands determining the possibility of their use in the constructions of control systems of water-water power and experimental reactors. Experimental batch of such products are fabricated.

-        

                    Technology for production is developed, structure and characteristics of wire of hafnium GFE-1 with diameter 2,5 mm are investigated. Production of experimental batch of hafnium electrodes for plasma cutting is developed.

    The way of production of body metallic glasses is developed; one of the component of such glasses was beryllium. Structure and properties of obtained materials are studied. Experimental pieces of such materials are produced for their use as first mirror for plasma diagnostic. The performed experiments have proved their serviceability.
