The intermetallics based on Ti-Al system are a relatively new class of high-temperature construction materials that combine unique physical and mechanical properties for use in aircraft engines, industrial gas turbines, or automotive industry. They are characterized by low density, good mechanical properties at high temperatures and good oxidation resistance. Addition of silicon into the Ti-Al alloys improves oxidation resistance and ultimate tensile strength in compression, but the complicated production limits wider use of these Ti-Al-Si intermetallic alloys. In this work, two main technologies of preparation of intermetallic compounds will be compared-melting and powder metallurgy.
