Distinct phase-selective corrosions of Ti-48Al alloy in aqueous electrolyte and molten salt
Source abstract
Abstract
Corrosion of Ti-48Al alloys, consisting of γ-TiAl phase and α 2-Ti 3 Al phase in lamellar structures, has been studied by electrochemical method at room temperature and molten salt method at elevated temperatures, respectively. Morphological, crystallographic, and microstructural studies provide direct evidence for γ-phase selective etching by the electrochemical corrosion at room temperature. In contrast, α 2 -phase selective etching of the Ti-48Al alloy occurred during molten salt corrosion, alongside α 2 -to-γ phase transformations at elevated temperatures. The distinct corrosion behaviors have been discussed and attributed to different chemical and physical properties between γ-TiAl and α 2-Ti 3Al phases within the Ti-48Al alloy.
