Effect of yttrium on oxygen content and microstructure of Ti-Al intermetallics
Original language description
The influence of metallic yttrium with a purity of 99.9 % on the microstructure and properties of cast Ti-47Al alloys prepared by vacuum induction melting was studied. The prepared alloys exhibited relatively homogeneous composition with dendritic structure formed by lamellar dendrites and g phase in interdendritic areas. The most yttrium rich phases were observed in the interdendritic areas, but were also observed within the dendrites. The composition of this phase corresponded to the Y2O3 oxide. It was found, that yttrium reduces the content of intersticial oxygen in the alloys due to high affinity to oxygen and also reduces primary and secondary arm spacing. Furthermore, the influence of yttrium on the solidification process of prepared alloys was studied by DTA (differential thermal analysis) and also was evaluated microhardness of prepared alloys.
