| Abstract: | TiAl based alloys have an excellent potential because of their low density and good elevated temperature properties, but the chief roadblock to their application is poor room temperature ductility. This paper summarized influencing factors of room temperature ductility of TiAl based alloys and some research progress in improving room temperature ductility through adding alloy elements and varying process method which can control the microstructure of TiAl based alloys. |
