| Abstract: | A new TiAl base alloy with high Nb content was developed with hot compressing tests and oxidizing examinations at high temperature. The results show that the alloy with fully lamellar microstructure has higher ultimate compressing strength and 0 2% proof strength than those with duplex microstructure at HT, but the plasticity is poor. The addition of high Nb to TiAl base alloys forms a layer concentrated Nb to alert the oxidation by promoting growth of an Al concentrated layer, thereby inhabiting formation of the more reactive Ti oxide. |
| Keywords: | TiAl containing high Nb hot compressing property oxidation resistance |
