| description | The invention relates to a lanthanum-cerium-yttrium-magnesium intermediate alloy and a preparation method thereof. The alloy comprises the elements, by weight, 15-17% of lanthanum, 29-33% of cerium, 40-50% of yttrium, 6-10% of magnesium, smaller than or equal to 0.20% of carbon, smaller than or equal to 0.10% of oxygen, and smaller than or equal to 0.50% of the sum of other impurity elements. Thelanthanum-cerium-yttrium-magnesium intermediate alloy is prepared by adopting a rare earth oxide multi-element eutectoid method and an intermittent heating method through electrolysis, continuous operation can be realized, production cost is greatly reduced, production efficiency is improved, good conditions are created for widely applying lanthanum, cerium and yttrium with low value to magnesiumalloys, and a novel multi-element rare earth-magnesium intermediate alloy preparation process is provided. The development requirements of rare earth magnesium alloys are met.
