An Anomalous Internal Oxidation of Dilute Cu-Ni Alloys at 800 °C under 1 atm O2

High Temperature Materials and Processes, 2012
The oxidation of six Cu-xNi alloys (x = 0.2, 0.6, 1, 2, 3, 4 at.%) was studied at 800 °C under 1 atm O2. All of the binary Cu-Ni alloys underwent an internal oxidation of Ni in the presence of an external scale of Cu2O and CuO, in agreement with the ...
