Production of Ti-10V-2Fe-3Al Alloy by Powder Metallurgy for Aerospace Applications 2006-01-2851

The production of titanium alloys by powder metallurgy (P/M) techniques is effective and cheap method to obtain pieces and components due to its low cost in comparison with conventional techniques. The P/M aims to transform metallic powders, using pressure and heat, by means of a thermal treatment (sintering). Ti-10V-2Fe-3Al alloy was developed specifically for aerospace applications. Samples were produced by mixing of initial metallic powders followed by cold uniaxial and isostatic pressing with subsequent densification by sintering at 1200 °C and 1400° in vacuum. The alloy was characterized by means of scanning electron microscopy and Vickers indentation and density. The sample present high densities and homogeneous microstructure.
