Distinctive Aspects of Hydrogenation Process of Ti33V33CR33 Produced by Abnormal Glow Discharge Plasma

The paper focuses on the description of the structural phase state and sorption characteristics of the Ti33V33Cr33 alloy. This alloy was synthesized by two different methods: abnormal glow discharge plasma (AGDP) melting and arc melting (AM). X-ray diffraction analysis revealed the presence of the main TiVCr phase with a BCC lattice, as well as the α-Ti phase in the AGDP method. In the case of the AM method, the formation of TiCrV and Ti3O phases is observed. The alloys synthesized by the AM method showed improved cyclic stability, while those obtained by the AGDP method demonstrated an increased maximum hydrogen capacity.
