- Abstract
- beta titanium alloys are more and more best choice materials for automotive and aerospace applications due to their high performance to density ratio. Among these alloys, the TIMETAL Ti-LCB is already used in the automotive industry since it presents excellent mechanical properties and a lower cost compared to other Ti alloys. The present study deals with the characterisation of the nucleation and growth of the alpha phase during several thermomechanical processes since the distribution and size of the alpha grains strongly influence the mechanical properties of the resulting microstructures. Several heat treatments were conducted after annealing. The resulting microstructures were characterised by SEM, TEM, XRD or EBSD. It is observed that the morphology and the volume fraction of the alpha phase is strongly dependent on the holding temperature, on the heating or cooling rate and on the beta grain size.
