Abstract

The kinetics and mechanisms of oxidelayer formation on Ti-Al-X alloys, specifically Ti-25Al-18Ta, Ti-30Al-2.7Nb, and Ti-43Al-11Nb have been studied. The activation energies for the oxide formation of each of the alloys used in this work were determined, and the values obtained were compared with those obtained by other researchers for identical alloys.
