Abstract
Ti-3A1-2.5V alloy was originally developed for the fabrication of hydraulic and fuel structures in conventional airplanes because it has intermediate performances (i.e. mechanical and corrosion resistance) compared to titanium and Ti-6A1-4V. The production of structural titanium components via powder metallurgy has been lately considered and a lot of interest has been shown from the aerospace industry due to the development of novel production methods which avoid the presence of chlorides. In this work the production and characterisation of the Ti-3A1-2.5V alloy produced considering the blending elemental approach is assessed. The alloy is consolidated by two conventional powder metallurgy routes (pressing and sintering and hot-pressing) in order to study the effect of the processing parameters. Complete diffusion of the alloying elements and homogeneous microstructures are generally achieved. The mechanical performances of the sintered products, which are comparable to those of the wrought alloy, are correlated to the relative density and microstructural features.
