Abstract Scope |
Metal matrix composites (MMCs) have significantly improved mechanical and thermal properties in a wide range of engineering fields. However, the complicated manufacturing process and low cost-effect ratio are significant limitations in applications. Additive manufacturing (AM) simplifies the process of components using metal matrix composite with the layer-by-layer printing strategy for complex shapes. After the heat-treatment design, binder jet AM (BJAM) can produce MMCs with ideal mechanical and thermal properties that are higher than the bulk materials. MMC design using BJAM is presented in this work, followed by sintering and infiltration through ICME design. Stainless Steel 316L is selected to be the matrix material. The infiltration of the liquid Inconel 718 fulfills the gaps and the pores between the solid stainless steel (SS)316L powder particles with a significantly minimized porosity. After aging, γ” and γ’ precipitation in Inconel 718 reinforces the matrix SS316L even further with a significantly enhanced strength. |
