%X The structures of rapidly solidified Cu_(30)Al_(70) alloy compared with conventional Cu_(30)Al_(70) alloy have been investigated. The structure in the rapidly solidified Cu_(30)Al_(70) alloy is more homogeneous than that of the conventional one and the aluminum phase is in the minor. The Al and Cu elements is also homogeneously distributed in the rapidly solidified Cu_(30)Al_(70) alloy. The rapidly solidified Raney copper has a smaller specific surface area and larger pore volume and diameter. The catalytic activity of rapidly solidified Raney copper is superior to that of the conventional Raney copper in hydrogenation.
