Microstructural and Mechanical Properties of Binary Ti-Rich Fe⁻Ti, Al-Rich Fe⁻Al, and Ti⁻Al Alloys.

Three series of binary, FeTi (Ti-rich), FeAl and TiAl (Al-rich) alloy samples were produced in an argon arc furnace. An annealing treatment of 72 h at 1000 °C was applied to the samples, giving rise to different equilibrium microstructures depending on chemical composition. Their mechanical properties were studied through the determination of elastic constants that measure the stiffness of the elaborated materials.
