superalloy TMS-82+ was studied under cyclic condition at 900 and 1 000 ℃ for 200 h in air. The oxidation kinetics for the superalloy at both exposure temperatures was explained... the thermal efficiency in industrial and jet engines due to their superior strength and better oxidation resistance. Several SC Ni-based superalloys have been developed by the modification of chemical......
