Structure of Titanium Alloys from System Ti-Al Prepared in Plasma Furnace and Vacuum Furnace

The article deals with possibilities of preparation of titanium alloys based on intermetallic phases from the system Ti-Al. Production of the TiAl alloys is difficult because of the reactivity of titanium. Therefore the alloys were prepared in plasma furnace and vacuum furnace. The preparation by these two various furnaces resulted in two different types of microstructures. The differences in microstructures of alloys were observed. Obtained microstructures were described and analysed. Measurement of hardnesses alloys and particular phases were performed.
