摘要：
The effect of minor substitution for Mn on the basic hydriding properties of Ti0.95Zr0.05Cr1.2Mn0.7X0.1 (X = Mn, Fe, Co or V) has been studied at 20 and 60 °C in order to find alloy-hydrogen systems for high-pressure applications in which high capacity, low hysteresis and flat pressure-composition-isotherm (PCI) plateaus are required. Samples have been synthesized by arc melting, and characterized by X-ray diffraction (XRD) and volumetric PCI measurements. Experimental evidence shows that even a small amount of V practically eliminates hysteresis while at the same time the PCI plateau slopes increase. Co-substitution also decreases hysteresis and keeps the PCI plateaus flat, but Fe-substitution does not seem to have any favourable effect on the basic hydriding properties. Possibility to study the relationship between hysteresis effect of high-pressure hydrides and their crystal structure is discussed.
