The Synthesis Method of Intermetallic Alloys Based on Ti–Cr with C14 and C36 Laves Phases for Hydrogen Storage

Abstract

The possibility of obtaining hydrogen storage materials based on TiCr₂ intermetallic compounds by the methods of melting in abnormal glow discharge plasma and electron beam melting is shown. The use of melting in abnormal glow discharge plasma leads to the formation of a Laves phase of the C36 structural type, while electron beam melting allows the C14-type Laves phase to be obtained. It is established that the formation of Laves phases of different structural types is associated with different cooling rates, which is caused by the specific features of the methods for synthesizing intermetallic compounds.
