- Traditional magnesium die casting alloys, particularly Mg-Al based alloys, face temperature limitations around 150°C due to unstable Al-rich phases at higher temperatures.
- High-temperature creep resistance of Mg-Al based die casting alloys is not ideal.
- Existing Al-free die-cast Mg-RE alloys, while developed for elevated temperatures, still face challenges in achieving higher working temperatures above 200°C and can become brittle with increased RE content, causing issues during die casting.
- Necessity of Research:
- There is a continuing need for improved processes for extracting magnesium from magnesium-bearing ores.
- Development of magnesium alloys capable of operating at demanding working temperatures above 200°C is crucial.
- High-pressure die casting (HPDC) capability for high-volume manufacturing of these alloys is essential for critical parts in internal combustion (IC) engines and power tools.
