| Abstract Scope |
The aerospace, automotive, and biomedical industries have seen an improvement with the advent of additive manufacturing processes, introducing ways to develop parts with complex geometries and better mechanical properties. Directed energy deposition is an additive manufacturing method that deposits materials under a high thermal gradient, allowing for fine microstructural control and the ability to produce metal matrix composites with enhanced mechanical properties and varied composition. In this work, the microstructure, tensile strength, and ductility of silicon carbide reinforced stainless steel 316L produced by wire laser directed energy deposition are examined for metal matrix composites of varying amounts of silicon carbide. The findings show that the introduction of silicon carbide improves tensile properties and hardness, due to the ceramic particles acting as nucleation agents for grain refinement. The weight percentage of the silicon carbide was also found to have a noticeable effect on the ductility of the material. |
