摘要：

The isothermal and thermocyclic oxidation behavior of various advanced single-crystal and directionally solidified superalloys in flowing air at a temperature of 2000 F(1093 C) has been studied. The methods included thermogravimetric measurements of oxidation rates and examination of the specimens by x-ray diffraction (XRD), optical metallography, and scanning electron microscopy (SEM). The oxidation mechanisms are discussed.
