Abstract

See full text

The present invention relates to a high-strength, high-corrosion resistance ternary magnesium alloy and a preparation method therefor, the magnesium alloy comprising the following element components by mass percentage: 8-12 wt % of Y, 0.6-3 wt % of Al and the remainder being Mg. The method comprises: (1) under a protective atmosphere, preparing a Mg—Y intermediate alloy, an aluminum ingot and a magnesium ingot into a magnesium alloy melt; (2) under a protective atmosphere, allowing the magnesium alloy melt to stand after stirring, then carrying out refining, degassing, and slag removal, allowing the magnesium alloy melt to stand again, then thermally insulating to obtain a magnesium alloy liquid; and (3) casting and molding the magnesium alloy liquid under a protective atmosphere, and forming a cast ingot; the three steps above ultimately obtain a high-strength, high-corrosion resistance ternary magnesium alloy.
