چکیده انگلیسی
Based on previous trial granulations of beryllides, a rotating electrode method (REM) was selected [[1], [2], [3]]. Furthermore, its experimental dataset is broad, covering beryllium and metallic pebbles. Rod-shaped beryllide blocks are necessary to fabricate beryllide pebbles via the REM. Hot isostatic pressing and casting have been proposed to synthesize beryllides. However, pure beryllium-based intermetallic compounds have very limited plasticity at high rotational speeds. The use of Be-V rods containing pure beryllium phase was considered a reasonable solution to this problem. The microstructure of Be-V rods and pebbles confirmed that the REM produced single-phase Be12V pebbles from multiphase Be-V rods. Special emphasis has been placed on the yield properties, size distribution, and sphericity of vanadium beryllide pebbles fabricated under different granulation conditions. The effect of rotational speed and electric current on pebble fabrication with the REM is discussed in this study. Taking into account the high costs and restricted availability of beryllium products, the perspective of material re-use was also considered by the process development and appropriate granulation trials were performed.
