process for preparing a hydrogen storage material comprising a severe plastic deformation operation

摘要

A process for preparing a hydrogen storage material comprising a severe plastic deformation operation. The present invention relates to a hydrogen storage material which is prepared by a process comprising a severe plastic deformation operation chosen between cold rolling, fast forging and curved extrusion: from a metallic material chosen from a metal and an alloy based on said metal, or - a compound based on a metallic material chosen from a metal and an alloy based on said metal, in which a hydride of said metal or a hydride of said alloy has been added. when the severe plastic deformation operation is performed on the metallic material, it is followed by an operation of adding to the metallic material a hydride of said metal or a hydride of said alloy and a dispersing operation.
