METHOD FOR PRODUCING Mg-REM-Ni BASE HYDROGEN OCCLUDING ALLOY

摘要

A method for producing an Mg-REM-Ni base hydrogen occluding alloy, which comprises melting raw materials of a rare earth metal and nickel in a melting furnace to thereby prepare a REM-Ni molten alloy, and then adding a raw material of Mg to the molten alloy, and then keeping the inside of the melting furnace at a specific pressure, to thereby prepare an Mg-REM-Ni molten alloy, and then cooling the resultant molten alloy at a specific cooling rate to solidify it. The above method can be suitably employed for alloying an Mg-REM-Ni base hydrogen occluding alloy, which is difficult to commercially produce, so as to have an objective composition precisely and with good efficiency.
