METHOD FOR MANUFACTURING MAGNESIUM BASED HYDROGEN STORAGE ALLOY POWDER WITH FINE-CRYSTALLINE PHASE SHOWING FAST DEHYDRIDING KINETIC AND MAGNESIUM BASED HYDROGEN STORAGE ALLOY POWDER WITH FINE-CRYSTALLINE PHASE SHOWING FAST DEHYDRIDING KINETIC MADE OF THE METHOD

摘要

present invention melted a rapidly solidified magnesium based alloy comprising the steps of solidification of the magnesium alloy to a heat treatment and to a method for producing a fine magnesium hydrogen storage alloy powder to prepare a magnesium -based alloy having a fine crystalline phase , ball milled to a magnesium -based alloy on the heat-treated fine crystal having a fine crystalline phase composed of pulverizing into fine powder, . ; can be used as the main ingredient of the cost according to the present invention, the magnesium to produce a magnesium-based hydrogen storage alloy fine powder having a fine crystalline phase to enhance the dehydrogenation rate at 300 .
