Etude de la formation des microstructures au cours du traitement de revenu dans les alliages de titane proche-β

Abstract : The aim of the study is to optimize heat traitements on forged titanium alloys for aerospace applications. This is the following of a first thesis working on the effect of heat treatement conditions on the development of microstructures in the Ti18 alloy. This first study shown very promising results and could have many benefits applications. That is why it is essential to acquire some informations on microstructure genesis in near-beta titane alloys. The aim is to understand phenomenons on phase transformation sequences in the family of near-beta titanium alloys (specificaly Ti555, NATIS, Ti18) and their influences on the final mecanical properties, with main application for landing gear.
