Comparative study of fusion relevant properties of Be12V and Be12Ti

Abstract Very similar brittle behavior of failure of Be 12 Ti and Be 12 V cylindrical specimens has been observed after testing under constant loads at 600 and 800 °C. Oxidation in air at 800 °C of both types of beryllide samples was studied. The thickness of oxidized layers before and after annealing tests was evaluated by means of Ion Beam Analysis using Rutherford backscattering technique. X-ray diffraction analysis revealed the formation of beryllium oxide layer on the surface of Be 12 Ti and Be 12 V samples. Some quantity of vanadium oxide V 2 O 5 on the surface of air-annealed vanadium beryllide sample related to a presence of vanadium-rich zones in initial material.
