摘要
The structural analysis of new hydrogen storage alloys, La5Mg2Ni23 and La(3)MgNi1(4,) was performed using HRTEM. As a result, these ternary system alloys were found to be mainly composed of stacked RNi5 (CaCu type) and R2Ni4 (Laves type) structure subunits in a superstructure arrangement. La5Mg2Ni23 alloy is composed of the primitive cell of three LaNi5 units and the primitive cell of two La2Mg2Ni4 units. La3MgNi14 alloy is composed of four LaNi5 and two La2Mg2Ni4 unit cells.
