The Relationship between Tensile Ductility Loss and Microstructures for the Hot Exposed γ-Tial Alloys

Abstract:

In this paper, the relationship between the tensile ductility loss and the conditions including the exposure process and microstructures for the hot exposed TiAl alloys was researched. The critical temperature corresponding to the ambient tensile ductility loss to 0.8% was sensitive to the microstructure. It was 800°C/100h exposure for the near fully lamella microstructure. Due to the oriented lamella, the near fully lamella microstructure was benefit for forming the oxide layer rich in Al to present further oxidation of the matrix.
