Recherche d’une alternative au TA6V - Relation entre microstructures et propriétés de deux alliages de titane αβ

Abstract : To reduce the processing cost of aeronautical parts, ongoing research is conducted to optimize material’s performances in their environment. One of the research project at IRT Saint-Exupéry is dedicated to the resistance against fatigue crack propagation of two titanium alloys, Ti54M and Ti575, potential candidates to replace TA6V. In that goal, the two alloys are subjected to thermal treatments in order to generate lamellar microstructure which improves the fatigue crack propagation resistance. After these treatments, the microstructures are characterized and the mechanical properties assessed. By comparing the results, the mechanical properties of Ti54M are equivalent to the mechanical properties of TA6V. So Ti54M could be an alternative alloy of the TA6V provided that complementary analyses are made
