Notes:
In this work, a lightweight Ti-10Mg-5Al (wt. %) alloy for structural components wasproduced by mechanical alloying. A metastable α-Ti(Al,Mg) solid solution was obtained after 50h of milling. Diffraction peaks ascribed to the Mg phase were detected in the XRD pattern of the sample heat treated at 600ºC. This phase tends to oxidize with the increase of temperature giving rise to MgO. The structure of the mechanically alloyed and 900ºC heat treated sample consisted of a Ti(Al) solid solution with dispersed MgO particles in the matrix. Hardness and Young’s modulusvalues obtained from ultramicrohardness tests confirm the strength improvement of the Ti-based alloy due to the MgO reinforcement
