Effect of annealing on microstructure and properties of yttrium alloyed intermetallics Ti-47Al
Original language description
Ti-Al intermetallic alloys, especially ?-TiAl alloys, are perspective materials for high-temperature applications in aerospace, automotive and power industries. However, their mechanical properties highly depend on the obtained microstructure. It has proved that the refinement of grain size led to improvement of mechanical properties. However, process parameters and alloy composition should be regulated in the narrow limits to achieve a low porosity and a microstructure required in the solid state. Theinfluence of annealing at different temperatures and different cooling conditions on the microstructure of the Ti-47Al binary alloy and also on the samples alloyed with yttrium in range from 0.1 to 0.4 at. % on microstructure was studied in this article.It was achieved several type of microstructures ? fully lamellar, nearly lamellar and duplex type. It was compared the influence of yttrium as refining element on the different types of structures and also the influence of this element o
