Study of the high temperature behaviour of titanium alloy Ti6242S under complex atmospheres : aeronautical applications
2018
The use of titanium alloys in many applications (transport, energy, chemistry,...) allows significant weight savings in relation to the good mechanical properties/density ratio of these materials. Since titanium alloys are employed at high temperatures (T>500°C), their behavior in such conditions has to be studied in severe conditions in order to understand degradation mechanisms. Moreover, some specific conditions can be met during application, like thermal cycling, water vapour or presence of salts. These parameters are known to influence oxidation behavior of titanium alloys.In this thesis work, oxidation behavior of an aeronautics titanium alloy (Ti6242S) has been studied in air and moi…
