Thermally stable nano-size ceramic particles are the preferred reinforcements for superalloys as they improve the alloys' microstructural stability and high-temperature properties. In this work, very dense and crack-free carbide-reinforced GTD222 (nickel-based superalloy) composites were prepared via selective laser melting (SLM). The distribution of TiC nanoparticles presents a three-dimensional (3D) network structure in the SLMed TiC/GTD222 composite. Mechanical testing revealed that the SLMed TiC/GTD222 composite has superior strength (UTS = 1320 MPa, YS = 1100 MPa) compared to the SLMed GTD222 superalloy. The GTD22 alloy reinforced with carbide nanoparticles’ distinctive microstructure and its excellent mechanical properties for is discussed.
