· JVASP-79163· Mg3Nb

Mg3Nb is an intermetallic compound composed of magnesium and niobium, representing a research-phase material in the magnesium-refractory metal family. This compound is primarily investigated for lightweight structural applications where thermal stability and high-temperature performance are critical, as niobium addition significantly improves the thermal creep resistance of magnesium-based systems compared to conventional Mg alloys. While not yet widely commercialized, Mg3Nb and related magnesium-niobium intermetallics show promise in aerospace and automotive contexts where reducing mass while maintaining strength at elevated temperatures could provide substantial fuel efficiency gains.
