Synthesis of quaternary nano‐intermetallic LaTi ₂ Ni ₅ Al ₄ with its hydrogen encapsulation and inspection using lithium‐hydride cell

Abstract

A novel alloy LaTi 2 Ni 5 Al 4 is investigated in this work. This quaternary composite belongs to the new generation of AB 3 intermetallics elaborated using the mechano-milling method. Several analytical techniques are operated in order to verify and confirm the crystallographic patterns following the growth progression of this nanoalloy. Starting from elemental metals, the authors show that they have basically LaTi 2 Ni 5 Al 4 major pattern corresponding to the symmetry crystal system (Trigonal R-3 m SG: 166). Structure refinement simulation demonstrates that performing this preparation with a laboratory grinding and milling benchtop, they obtain a maximum proportion of AB 3 intermetallic alloy after 20 h of metallurgy work processing. The proposition of useful stabilised solid-hydrogen encapsulation is highlighted and tested using a specific lithium-hydride cell.
