Selective Laser Melting of Mixed EP648-Alumina Powder

Selective laser melting (SLM) technology makes it possible to produce complex shape metallic and metal-matrix composite (MMC) bulk parts from powder feedstock. This paper is devoted to selective laser melting of mechanically mixed metal (gas atomized EP648 alloy) and ceramic (alumina) powders. Four...

Zusammenfassung:Selective laser melting (SLM) technology makes it possible to produce complex shape metallic and metal-matrix composite (MMC) bulk parts from powder feedstock. This paper is devoted to selective laser melting of mechanically mixed metal (gas atomized EP648 alloy) and ceramic (alumina) powders. Four 10x10x5 mm specimen were successfully manufactured using different process parameters. Obtained MMC specimen were characterized by scanning electron microscopy. A possibility of manufacturing of dense EP648-alumina MMC by SLM using two-component mixed powder was shown
