ABSTRACT:
The method disclosed herein involves the addition of small quantities of elements appearing for the most part in Groups IA, IIA and IIIB of the Periodic Table to the base alloy composition. These elements, as ions, enter into the protective oxide scale and modify predominantly anion and to a lesser extent cation transport through the oxide scale, greatly reducing the amount of oxidation observed due to elevated temperature exposure.
