Tensile creep tests were conducted on directionally solidified TiAl alloys to discern the effect of alloying and lamellar orientation. A seeding technique was used to align the TiAl/Ti 3 Al lamellar structure parallel to the growth direction for alloys of Ti-47Al, Ti-46Al-0.5Si-0.5X (X=Re, W, Mo, and Cr), and Ti-46Al-1.5Mo-0.2C (at.%). Tensile creep tests were performed at 750<space> o C using applied stresses of 210 and 240 MPa. Aligning the lamellar microstructure greatly enhances the creep resistance which can further be improved by additional alloying.
