摘要： 测定了Zr0.9Ti0.1(Ni,Co,Mn,V)2+a 贮氢合金在铸态、快淬态及快淬合金经不同退火温度处理后的压力-组成-温度曲线，计算了它们的焓变值，测试了其电化学容量. 结果表明：快淬后的贮氢合金随退火温度的增加，焓变值和放电容量也增加. 在1173 K温度下退火处理的贮氢合金，其放电容量(379 mA×h/g)较铸态合金好，但它的活化性能不如铸态合金.

Abstract: The pressure-composition-temperature isotherms desorbtion were studied for Zr0.9Ti0.1(Ni,Co,Mn,V)2+a treated by casting, melt-spinning and annealing at different temperatures respectively. The enthalpies and discharge capacities of the alloys were tested. The results indicated that the absolute value of enthalpy and capacity were increased with annealing temperatures. The alloy annealed at 1173 K had a higher capacity (379 mA×h/g) than that of cast alloy, but its activation was worse than that of cast alloy.
