2. The superalloy in a turbine blade, Inconel 718, has a room-temperature strength equal to 1.2 GPa. It decreases with temperature as: =00 1- T-To Tm-To where To is the room temperature and Tm is the melting temperature (=1,400 C). Given: 8,000 rpm Disc radius: 60 cm Cross sectional area: 15 cm Length: 25 cm Alloy density: 8.5 g/cm At what temperature will the turbine flow plastically under the influence of the centripetal forces? (10 points) 2. The superalloy in a turbine blade, Inconel 718, has a room-temperature strength equal to 1.2 GPa.
