Oxygen permeability through internal oxidation zone in Fe–Cr alloys under dry and humid conditions at 973 and 1 073 K

Oxygen permeability through internal oxidation zone in Fe–Cr alloys under dry and humid conditions at 973 and 1 073 K

Internal oxidation of Fe–Cr alloys were investigated in dry and humid atmospheres at temperatures of 973 and 1 073 K in order to clarify the effect of humidity on the oxygen permeability in internal oxidation zone. The oxygen partial pressure in the chamber was fixed by Fe/FeO powder mixture. The...
