摘要	Room temperature compression properties of Ti-51Al-(1 similar to 2)X and Ti-26Al-(1 similar to 2)X alloys (X=V, Cr, Mn, Fe, Co, Ni, Zr, Nh, Mo, Ta, Ga or Sn) were measured in order to examine how the compression deformability correlates with the site occupancies of the alloying elements in gamma-TiAl and alpha(2)-Ti3Al. The results showed that, for the gamma phase, the compression ratio is not related to the site preference of the alloying elements in a simple way. For the alpha(2) phase, the following correlation was observed between the compression ratio and the site occupancies of the investigated elements, those which occupy Al sites decrease the deformability, while those occupying Ti sites (except V) improve the deformability of the alpha(2) phase. Compression properties of dual-phase TiAl alloys based on Ti-46Al-(1, 3, 5)X were also measured at room temperature to test a hypothetical mechanism of ductilization based on mechanical compatibility at phase interface. It was concluded that no simple relationship exists between the deformability of the dual-phase alloys and the properties of their constituent phases.
