Abstract

The oxidation behavior of superalloy IN 713 fabricated by metal injection molding (MIM) was investigated and compared with standard cast material plus hot isostatic pressing (Cast + HIP). The carbon content of MIM alloys varied in the experiments due to the use of different starting powders. At all temperatures and times investigated, weight gain increased strongly with carbon content. Carbon in the alloys was present mainly in the form of carbides. Carbides react with oxygen during oxide scale formation. Microscopy showed that selective oxidation of carbides led to the formation of protrusions and cracks in the oxide layer. In this way, the protective effect of the oxide scale was weakened.
