Abstract
This work aims to describe the effect of alloying by transition metals (Co, Cr, Cu, Fe, Ni, Mo) on the structure and properties of TiAl15Si15 alloy prepared by SHS technique. Results show that alloying elements do not form their own phases in detectable amounts, being dissolved in titanium silicide or aluminide. Co, Cu and Ni were determined mainly in aluminide, while iron was found predominantly in the silicide phase. Chromium and molybdenum dissolve in both aluminide and silicide in almost comparable amounts. All applied alloying elements increase the wear resistance and the oxidation resistance at 1000 °C, but reduce the room-temperature mechanical properties. Molybdenum-alloyed material exhibits the best oxidation resistance, followed by chromium-containing alloy. These alloys are also characterized by exceptional thermal stability.
