About dislocation density distribution in titanium alloys after hot-deformation in the α+β domain

Résumé

The initial microstructure to be deformed has great influence on plastic deformation and on the storage of dislocations. In turn, microstructure evolution is tightly correlated to the organization and distribution of dislocations. The assessment of dislocation density is quite a laborious task, where all possible different approaches only allow for getting more or less accurate estimates, and the task is even harder when dealing with dual phase materials. Aim of this work : Estimate an compare the dislocation density in the Ti-6Al-4V alloy, with equiaxed and lamellar morphology, after hot-deformation in the two-phase domain, by two different approaches : Macroscopic and Microscopic.
