Oxidation behavior of titanium aluminides
Journal de Physique IV : Proceedings
Results from an ongoing study of the high temperature oxidation of intermetallic compounds in the Ti-Al system are presented. The oxidation behavior of alloys based on TiAl (y) has been found to be extremely complex depending on temperature and atmosphere composition. Protective alumina scales are formed in pure O2 up to a critical temperature above which a mixed Ti02/A1203 scale forms and grows at rates which are orders-of-magnitude faster than that of alumina. This phenomenon is believed todoi:10.1051/jp4:1993941 fatcat:7gqwywpb5fbljks4dzdjnxolx4
