<正> 在新能源材料研究中,LaNi_5型贮氢材料引起人们的极大兴趣,尤其重视研究第三元素取代后的LaNi_(5-x)Mx(M为过渡族元素)合金的贮氢性能。本文研究以Fe代Ni后含La16.7at.-％的Ni-Fe-La三元合金状态图及合金成分与贮氢性能的关系。 一、实验部分 熔制合金所用的原料是纯度为99.9at.-％的Fe和Ni,纯度为99.5at.-％的La,按照LaNi_(5-x)Fe_x的不同化学组分配制,在非自耗真空电弧炉内充高纯Ar保护熔炼。共制备15个样品,每个样品重量约为30g,每种合金经6次以上反复熔炼。熔制后的试样
The phase equilibrium relationship of the Ni-Fe-16.7 at.-%La system has been investigated by means of X-ray diffraction and DTA. The Ni-riched region has a peritectic reaction. A new hexagonal intermetallic compound LaNi_3Fe_2is identified. The absorption and desorption of hydrogen by the system and by this new compound were also examined.
