Thermal, Microstructural and Electrochemical Hydriding Performance of a Mg65Ni20Cu5Y10 Metallic Glass Catalyzed by CNT and Processed by High-Pressure Torsion

A Mg65Ni20Cu5Y10 metallic glass was produced by melt spinning and mixed with a 5 wt.% multiwall carbon nanotube additive in high-energy ball mill. Subsequently, the composite mixture exposed to high-pressure torsion deformation different numbers. Complimentary XRD DSC experiments confirmed exceptional structural thermal stability of amorphous phase against severe plastic deformation. Combined high-resolution transmission electron microscopy observations fast Fourier transform analysis revealed deformation-induced Mg2Ni nanocrystals, together morphological nanotubes. The electrochemical hydrogen discharge capacity severely deformed pure substantially lower than that samples for several cycles. It also established most sample containing nanotubes exhibited drastic breakdown after eight
