La2O3 effects on TZM alloy recovery, recrystallization and mechanical properties

Titanium, zirconium and molybdenum (TZM) alloy with different amounts of rare earth lanthanum oxide was prepared by powder metallurgy into 0.5 mm thick sheets. The effects of the La2O3 content on recrystallization temperature and mechanical properties of the TZM alloy were studied. La2O3 increased the recrystallization and recovery temperature of the TZM alloy and increased its tensile strength and elongation.
