Abstract null null The effect of solution treatment on the microstructure and creep properties of forged TiAl–Nb alloys was investigated. The results showed that the microstructure of forged alloy mainly consisted of γ/α2 lamellar colonies and fine equiaxed recrystallized γ/α2 grains. During the solution treatment the microstructure of the alloy transformed into a fully lamellar structure due to the lamellar colonies growth by consuming equiaxed grains. Compared with the forged alloy the creep l...

Abstract By means of creep properties measurement and microstructure observation, the deformation and damage behavior of an as-cast TiAl-Nb alloy during creep at temperature near 750 °C were investigated. The results showed that the microstructure of the alloy consisted of lamellar γ/α2 phase, and the boundaries consisted of γ phase located in between lamellar γ/α2 phases with different orientations. In the latter stage of creep, the dislocation networks appeared in the interfaces of lamellar γ/...

Abstract By means of creep properties measurement and microstructure observation, an investigation has been made into the creep behaviors and deformation features of TiAl–Nb alloy with various states at high temperature. Results show that the microstructure of as-cast alloys consists mainly of lamellar γ/α 2 phases with various orientations, the boundaries located in between the ones consist of single γ phase. The bigger plastic deformation of alloy during forging may refine the grains and incre...
