Benefits of technology

The magnesium mother alloy enhances hardness, corrosion resistance, and ignition temperature while maintaining the original alloy composition, allowing for cost-effective production and reusability without further scandium addition, and when added to aluminum alloys, it maintains their properties without deterioration.

Problems solved by technology

However, scandium (Sc) is a rare earth material, and the amount of scandium (Sc) existing on the earth is too small.
Furthermore, there is a difficulty in separating scandium (Sc) from a mineral, and thus scandium (Sc) is very expensive.
Unfortunately, when Sc2O3 is directly added into aluminum alloys, various alloy properties such as hardness, corrosion resistance and weldability are deteriorated due to oxides of scandium (Sc).

Abstract

Disclosed are a magnesium mother alloy, a manufacturing method thereof, a metal alloy using the same, and a method of manufacturing the metal alloy. In particular, there are provided a magnesium mother alloy with improved oxidation and ignition properties, and a manufacturing method thereof, and also provided a metal alloy with low cost that is suitable for design purposes using the magnesium mother alloy, and a method of manufacturing the metal alloy. The magnesium mother alloy includes a plurality of magnesium grains, and scandium dissolved in the magnesium grains, or a scandium compound crystallized at grain boundaries which are not inside but outside the magnesium grains. Also, the metal alloy suitable for design purposes is manufactured at low cost by adding the magnesium mother alloy containing scandium into a magnesium alloy or an aluminum alloy.
