Method for preparing a material for storing hydrogen, including an extreme plastic deformation operation

摘要

The invention relates to a material for storing hydrogen, which is prepared by a method including an extreme plastic deformation operation selected from cold-rolling, quick-forging, and extrusion-bending, performed on a metal material selected from among a given metal and an alloy containing said metal, or on a compound containing a metal material selected from among a given metal and an alloy containing said metal and to which a hydride of said metal or a hydride of said alloy has been added. When the extreme plastic deformation operation is carried out on the metal material, it is followed by an operation of adding, to the metal material, a hydride of said metal or a hydride of said alloy, as well as by a dispersing operation.
