Sintering of Si<sub>3</sub>N<sub>4</sub>–SiC–MoSi<sub>2</sub> composites additively manufactured by Multi Material Jetting
Abstract
<jats:title>Abstract</jats:title><jats:p>The aim of this work was to investigate the sintering behavior of Si<jats:sub>3</jats:sub>N<jats:sub>4</jats:sub>–SiC–MoSi<jats:sub>2</jats:sub> composites manufactured by the Multi Material Jetting (MMJ) process. Therefore, electrically conductive and insulating Si<jats:sub>3</jats:sub>N<jats:sub>4</jats:sub>–SiC–MoSi<jats:sub>2</jats:sub> composites were printed using MMJ. Samples were sintered in a gas‐pressure furnace at 6 and 31 atm, respectively. The density, microstructure, and crystalline phase composition were investigated, and the results discussed regarding the phase stability of the Si<jats:sub>3</jats:sub>N<jats:sub>4</jats:sub>–SiC–MoSi<jats:sub>2</jats:sub> composites. The results show that the nitrogen pressure must be set carefully to avoid the formation of Mo<jats:sub>5</jats:sub>Si<jats:sub>3</jats:sub> or Mo<jats:sub>4.8</jats:sub>Si<jats:sub>3</jats:sub>C<jats:sub>0.6</jats:sub> on the one hand and to prevent the decomposition of the phases into a Si‐containing melt on the other.</jats:p>
