摘要：
The oxidation behavior of the Co-base superalloy DZ40M was studied in air at 900-1100 °C for times of up to 2000 hr. The results indicated that this alloy can grow a protective oxide scale at 900 and 1000 °C during isothermal oxidation, but not at 1100 °C because of serious cracking and spalling of the oxide scales. Moreover, an internal-precipitate zone formed in the subsurface region of the alloy at all temperatures and times. The precipitates were rich in Cr in the vicinity of the alloy-scale interface and rich in Al deep in the alloy. The internal-precipitate morphology changed from a granular to needlelike shape with increasing oxidation temperature.
