摘要：

By high temperature pack rolling, the first high-Nb TiAl sheet with the thickness of 2.6 mm has been successfully fabricated on a conventional rolling mill. The overall rolling reduction is about 70%, and the surface condition of the sheet is very good. Microstructure observation indicates that during the high temperature rolling, dynamic recrystallization takes place. But the microstructure is not significantly refined by this recrystallization probably on account of the grain growth that occurs during reheating between rolling passes and final furnaccooling.
