GAMMA TITANIUM ALUMINIDES FOR HIGH RELIABILITY COMPONENTS (ALTIVA)

Gamma-titanium aluminides are an important new class of turbine engine materials because they can provide increased thrust to weight ratios and improved fuel efficiency. The aim of the ALTIVA project was to investigate the deformation and fracture mechanisms of a Ti4522XD alloy under service conditions. In-situ tests, carried out in a scanning electron microscope at temperatures ranging from 25 to 700°C, in combination with EBSD-assisted slip trace analysis allowed to detect in real time the fracture initiation and propagation sites and, thus, provided guidelines for an optimized design of these materials (Muñoz-Moreno et al. Materials Science and Engineering, 2014).
