The role of niobium in zirconium alloys | Western Alloys Co., Limited

The niobium ion is solid-dissolved in Zr with the valence of +5 and replaces the zirconium ion with the valence of +4, and the oxygen ion vacancy is reduced. The reduction of oxygen vacancies can stabilize the tetragonal ZrO2 and hinder the migration of oxygen ions. Nb has a relatively high strengthening effect on zirconium.
