摘要：

Single phase Fell intermetallic and FeTi-3.1 mass % V alloy were synthesized by vacuum arc melting using high purity elemental constituents. The crystal structure of both, FeTi intermetallic and FeTi-3.1 mass % V alloy was found to be of CsCl-type. Under similar annealing conditions, crystallite size of FeTi-3.1 mass %V alloy was markedly smaller than that of Fell intermetallic. Hydrogen absorption in FeTi intermetallic and FeTi-3.1 mass % V alloy was studied in a thermobalance attached to a Sieverts apparatus at a temperature of 327 K under 0.2 MPa hydrogen pressure. The hydrogen absorption in vanadium alloyed FeTi matrix was significantly faster than in the pure intermetallic. The maximum amount of hydrogen absorbed in the FeTi intermetallic and FeTi-3.1 mass % V alloy was of 1.2 and 1.1 mass % respectively. (C) 2014 Elsevier Ltd. All rights reserved.
