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.
