High-temperature Oxidation of Ni-based Inconel 713 Alloys at 800-1100℃ in Air Lee, Dong-Bok;
The Ni-based superalloy, Inconel 713, was oxidized at for 50 and 100 hours in air. It displayed excellent oxidation resistance, forming a few micrometer-thick scales. The major scale was . Other scales formed were , and . Generally, uniform oxidation occurred over the alloy surface, resulting in the formation of with and without . Other oxides such as and sometimes also formed. Locally, nodular oxidation occurred at the nodules that consisted of diverse alloying elements. The scales were adherent at . However, they spalled a little at .
