| Popis: | A novel alloy LaTi2Ni5Al4 is investigated in this work. This quaternary composite belongs to the new generation of AB3 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 LaTi2Ni5Al4 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 AB3 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. |
