In the field of composites, interpenetrating metal-ceramic composites (IMCC) are currently still a relative rarity. Due to the continuous phases of the supporting ceramic and the ductile metal, a reduced coefficient of thermal expansion and a higher wear resistance, as well as increased specific- and fracture properties are given. However, with this material, preparation for metallographic investigation is a major challenge, as it must be suitable for both the brittle ceramic and the ductile alloy. In the present work, a preparation route was developed for an AlSi10Mg-Al₂O₃ composite to achieve a surface quality that would allow SEM EBSD recordings. The basis for this was a routine developed by former researchers in which, however, indentations due to ceramic particles occurred in the soft metallic phase in some cases during polishing; this was systematically improved and finally a suitable process routine developed.
