Nanoscale Studies of the Early Stages of Oxidation of a TiAl-Base Alloy

Corrosion of Intermetallics

“…This state can be taken as the fingerprint for the reduced TiO 2 surface, indicating the presence of Ti 2 O 3 . The energy for this state, estimated from the STS measurement, is in agreement with previous results (Ref 71).…”

Phase Investigations Under Steam Oxidation Process at 800 °C for 1000 h of Advanced Steels and Ni-Based Alloys

“…It is believed that higher mass gain for c 0 -strengthened alloys occurred due to the development of a TiO 2 phase on the surface. It is well known that the TiO 2 phase possesses a high number of defects in the crystal structure and is often responsible for accelerated mass gain in TiAl alloys [28,29]. Karake et al [30] indicated that the doubly ionised oxygen vacancies are responsible for the kinetic growth rate of TiO 2 scales over Ti-rich alloy and accelerated weight gain.…”
