## Abstract

New ternary Mg-Ni-Mn intermetallics have been successfully synthesized by High Energy Ball Milling (HEBM) and have been studied as possible materials for efficient hydrogen storage applications. The microstructures of the as-cast and milled alloys were characterized by means of X-ray Powder Diffraction (XRD) and Scanning Electron Microscopy (SEM) both prior and after the hydrogenation process, while the hydrogen storage characteristics (P-c-T) and the kinetics were measured by using a commercial and automatically controlled Sievert-type apparatus. The hydrogenation and dehydrogenation measurements were performed at four different temperatures 150-200-250-300oC and the results showed that the kinetics for both the hydrogenation and dehydrogenation process are very fast for operation temperatures 250 and 300oC, but for temperatures below 200oC the hydrogenation process becomes very slow and the dehydrogenation process cannot be achieved.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
