Abstract:The effects of Pb addition on the mechanieal properties , microstructure, crystal structureand fracture characters were investigated. It has been found that the room-temporature mechani-eal properties of TiAl based alloy can be improved by Pb addition, the reasons for which havebeen explainetl based on the changes in microstructure and fracture characters with Pb addition.
Key words: TiAl intermetallic compound alloying room temperature mechanical properties
