Abstract Scope |
Metal matrix nanocomposites (MMNCs) with uniform distribution of nanoscale ceramic particles can show dramatically improved mechanical properties as compared to the matrix materials. However, when the size of the nanoparticles is small and the volume fraction of nanoparticles is high, it is very difficult to disperse them uniformly in the metal matrix. Here we report the dense stainless steel nanocomposites with uniform distributed ceramic nanoparticles were successfully fabricated by ball milling and selective laser melting (SLM). Detailed microstructure characterization and analysis reveal that the dispersion of nanoparticles in the SLMed sample strongly depends on the dispersion of nanoparticles in the feedstock powders. Our research provides a promising approach to manufacture MMNCs with uniform dispersion of nanoparticles by additive manufacturing process. |
