A brief discussion on the tensile creep deformation behaviour of wrought single-phase ?-TiAl

Creep deformation behaviour in single phase $\gamma$-TiAl alloy has been an extensively studied topic since the late 1970s. A lot of literatures have reported creep alloys, manufactured using different processing techniques. The present discussion revisits original work on understanding tensile wrought single-phase by Hayes et al and is aimed to develop steady state creep, through strain vs rate ln(strain rate) plots. Besides, it also attempts study variation stress exponent with temperature between 760 900C also, determine activation energies two most common approaches, namely: Zener-Hollomon Sherby-Dorn for levels 69.4 103.4 MPa 900C.
