Gamma based TiAl alloys are currently seen as potential materials for high temperature structural applications due to their high specific strength, stiffness at elevated temperatures, and good creep and oxidation resistance. However, their poor ductility at ambient temperature and its poor formability prevents their practical applications. In this paper, a detailed investigation of microstructural evolution and mechanical properties of a tempered massive gamma TiAl alloy has been undertaken. The isothermally forged alloy was also investigated to determine which provides better mechanical properties.
