Title:
REAR EARTH DOPED MG-BASED HYDROGEN STORAGE ALLOY
Document Type and Number:
WIPO Patent Application WO/2020/006843
Kind Code:
A1
Abstract:
A rear earth doped Mg-based hydrogen storage alloy. The rear earth doped Mg-based hydrogen storage alloy is prepared by means of the following method: providing Mg, Ce, Gd, Y, Ni, and Al metal raw materials; weighing the Mg, Ce, Gd, Y, Ni, and Al metal raw materials according to a preset chemical formula; performing first vacuum melting on the weighed Mg, Ce, Gd, Y, Ni, and Al metal raw materials to obtain a primary Mg alloy ingot; crushing and ball-milling the primary Mg alloy ingot to obtain primary magnesium alloy powder; pressing the primary magnesium alloy powder into a loose alloy ingot by means of cold isostatic pressing; hot-pressing the loose alloy ingot to obtain a dense alloy ingot; performing second vacuum melting on the dense alloy ingot to obtain a second Mg alloy ingot; crushing the second Mg alloy ingot; and performing single-roller quenching on the crushed second Mg alloy ingot to obtain the rare earth doped Mg-based hydrogen storage alloy.
