Composites a base de magnesi per a l'emmagatzematge d'hidrogen

Magnesium based alloys have been intensively studied during the last decades as potential candidates for hydrogen storage systems. Due to their higher hydrogen storage capacity, lower density and natural abundance, as compared with other hydrogen storage alloys (e.g. AB5, AB2 alloys), they are considered as the most promising materials for storing hydrogen. In the present project we intend to synthesize different Mg2-xMxNi (M=Ti,Zr,V,Al) alloys by MA and to optimise their composition and microstructure (nanocrystalline, nano-/amorphous) to improve the hydrogen sorption characteristics of these type of alloys.
