Additive Manufacturing (AM) holds strong potential for the formation of a new class of multifunctional nanocomposites. Selective laser melting, as a promising AM fabrication route, was applied to produce nanocrystalline TiB2-reinforced H13 steel matrix nanocomposites. Uniformly dispersed TiB2 particles were obtained and fine homogenous needle-shaped martensitic microstructures were observed. The microstructural and mechanical properties of SLM-processed nanocomposites were sensitive to the TiB2 addition. Relative to the unreinforced H13 steel part, the TiB2/ H13 steel nanocomposites parts with the novel architecture exhibited much higher hardness due to the combined effects of grain refinements and grain boundary strengthening.
