| 摘要 | Shot peening, although generally accepted as a useful surface treatment method to improve oxidation resistance of Ni-, Co- and Fe-based alloys, has been less applied to TiAl based alloys. This work shows that a shot peening treatment converts the Ti-45Al-2Nb-2Mn-1B alloy from thermally growing TiO2-Al2O3 mixed oxides to an exclusive Al2O3 in air at 900 degrees C. The basic reason for this is that the shot peening catalyzes formation of an alpha-Al2O3 thin film, which prevents Ti of the alloy from oxidation at the high temperature. The slow oxidation of the shot peened alloy mitigates the degradation of typical gamma/alpha 2 lamellar microstructure. |
