Alloys and Alloying Elements

The corrosion resistance of uranium is increased with the addition of some alloying elements. The most common alloying elements are titanium, molybdenum, niobium, and zirconium. The addition of these elements promotes the formation of γ-phase (cubic) rather than the α-phase (orthorhombic) of unalloyed uranium, which increases the corrosion resistance.
