【 摘 要 】

The oxidation behavior of FeCo(NbZr)B(Cu) alloy series was studied. After heating up to 1073 K, an oxide layer similar to 1 mu m thick with a two-layer structure can be identified previous to a sharp interface between the oxide layer and alloy matrix, where no oxygen is detected. The coercivity of nanocrystallized samples increases, independently of the gas environment, during additional long-time-annealing without a significant change of the microstructure.
