Brief description Development of Creep Resistant TiAl Alloys for High Temperature Structural Applications. TiAl based alloys are being developed as high temperature structural materials for aerospace and automotive applications and thus their creep resistance (long-term strength at elevated temperatures) is critical. This project aims at developing creep resistant TiAl alloys through a combination of addition of rare earth and severe plastic deformation. It is expected that a refined and stablised microstructure consisting of submicron lamellar grains and nanosized lamellae be obtained. This will result in a highly creep resistant prototype TiAl material and leads eventually to the development of commercial TiAl alloys.
