Magnesium Erbium Master Alloy (Mg-Er Alloy) Description

Magnesium Erbium Master Alloy is a specialized alloy composed of magnesium and erbium, a rare earth element. This alloy is primarily used to enhance the mechanical properties and high-temperature performance of magnesium-based alloys. The addition of erbium to magnesium significantly improves its strength, heat resistance, and corrosion resistance, making it an ideal material for applications in demanding environments.

1.       Common Preparation Methods

Magnesium Erbium Master Alloy (Mg-Er Alloy) is typically prepared by melting high-purity magnesium and adding the appropriate amount of erbium under a controlled protective atmosphere (such as argon or a CO₂ + SF₆ gas mixture) to prevent oxidation. The process is usually carried out in a resistance or induction furnace with a graphite or steel crucible. Erbium is gradually introduced into the molten magnesium at elevated temperatures (typically around 700-750°C), ensuring complete dissolution and uniform distribution. The molten alloy is then stirred, held for homogenization, and cast into molds or ingots for solidification. Rapid cooling may be applied to minimize segregation and improve microstructure uniformity.
