Nuclear Materials and Properties

Hydrogen desorption and electrode properties of Zr0.8Ti0.2(V0.3Ni0.6M0.1)2 alloys (MSi, Mn, Co, Mo) were studied. The Si, Mn-substituted alloys had the C14 Laves phase structure, but the Co, Mo-added alloys had the C15 Laves phase structure. The pressure-composition desorption isotherms were sloped. Among the four additive elements, manganese led to the fastest activation and highest discharge capacity and cobalt to the longest cycle life. These features were attributed to the different microstructures.
