γ-TiAl based alloys are very perspective materials thanks to their outstanding properties, such as high specific strength, low density, high modulus of elasticity, good oxidation resistance and resistance to creep. At present, the greatest attention is paid to TiAl alloys which contain relatively high content of refractory metals such as Nb, Ta, Mo and W. The main objective of this paper is, how to transform the refractory W, Ta or Nb into the form of master alloys, suitable for preparation of heavy alloyed γ-TiAl intermetallic alloys and characterize the homogeneity, microstructure and other properties (oxygen content, melting temperature) important for their further using.
