Abstract

Titanium aluminide base intermetallics posses excellent high temperature strength and low density. However, low room temperature ductility and toughness restrict the application of titanium aluminide base intermetallics for structural components. Effect of aluminium content and ternary addition on the fracture toughness of gamma base titanium aluminides were investigated at room and elevated temperatures. From the experimental results, it was found that microstructure has strong influence on the room and elevated temperature fracture toughness while ternary addition has no effect on the room temperature fracture toughness but affect at high temperatures. Fracture surface morphology depended on the microstructure and test temperature and had strong correlation with the fracture toughness.
