Impact of a post-casting homogenization treatment on the high-temperature oxidation resistance of a Cu-Ni-Fe alloy
Source abstract
Abstract
Abstract Homogeneous Cu65Ni20Fe15 (wt.%) alloy, which is a promising anode material for zero-carbon Al production, was successfully produced by casting followed by heat treatment at 1070 °C for 50 h. At 700 °C, the homogenization procedure increases the oxidation resistance of the homogeneous Cu-Ni-Fe alloy, as confirmed by the decreased weight gain (34% less after 20 h) and parabolic rate constant kp (by a factor of 2.5) compared to the as-cast alloy. The oxide scale formed on the homogenized alloy is thinner, more compact and coherent, consisting of a CuO outer layer and a (NiO + Fe3O4)-rich inner layer.
