چکیده انگلیسی
ⶠThe microstructural modification of the LaMg12 alloy was performed by means of the Rapid Solidification technique. The structure and microstructure of the alloys were closely related to the solidification rate. ⶠThree types of the parent crystal structures, including, for the first time reported for the La-Mg alloys, hexagonal TbCu7 type, together with the earlier known tetragonal ThMn12 and orthorhombic LaMg11 types, were revealed. ⶠFine nanostructuring of the material leads to a complete recombination process to form LaMg11 from LaH3 and MgH2 and to the enhancement of hydrogen exchange. ⶠRapid Solidification proves to be an efficient route in favourably modifying of the hydrogenation behaviour of the intermetallics of rare earth metals and magnesium.
