| 中文摘要 | The effect of atomic order on environmental embrittlement of an Fe3Al-based alloy was studied. The ordered B2 and DO3 structures are much more susceptible to the test environments (air versus vacuum) than the disordered structure. The embrittlement index, I, of B-2, DO3 and disordered structures is 62.1%, 62.5% and 21.7%, respectively. The disordered Fe-Al alloy showed the transgranular cleavage fracture mode whenever tested in vacuum or in air. A mixed intergranular/transgranular cleavage fracture mode was observed for both ordered alloys tested in vacuum. When tested in air, the B2 alloy continued to fracture via the mixed mode, while the DO3 alloy exhibited mainly transgranular cleavage fracture. |
