TiAl has a density half of the density of nickel-based superalloys (1), high strength and good thermal stability (9). Despite this TiAl is not a material used in a wide range of structural applications. A reason for this is believed to be TiAl’s brittleness which makes it hard to process with conventional manufacturing methods. Manufacturing methods like casting and forging have been applied but they are accompanied with problems and limitations (10). Due to the low fracture toughness post-processing and machining is also challenging without fracture the material (2). For example to replace nickel-based superalloys with TiAl in low pressure turbines the material must be able to be manufactured to a blade with complex shape. Production is not easy and limits a cost-effective use of TiAl (4).
