Effects of high temperature treatments in air and argon on the magnetic properties of HITPERM alloys

The oxidation behavior of FeCo(NbZr)B(Cu) alloy series was studied. After heating up to 1073 K, an oxide layer View the MathML source∼1μm 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 coerci...

Descrição
Resumo:The oxidation behavior of FeCo(NbZr)B(Cu) alloy series was studied. After heating up to 1073 K, an oxide layer View the MathML source∼1μm 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
