Title: Strengthening of ferrous binder jet 3D printed components through bronze infiltration

Abstract

Fully-dense, net shape objects have been fabricated from a rapidly-solidified ferrous powder using binder-jet 3D printing and molten bronze infiltration. X-ray diffraction, scanning electron microscopy, and differential thermal analysis were used to characterize the structural evolution of the powder feedstock during an infiltration heating cycle. Microindentation and bend tests were performed on the infiltrated material to evaluate its mechanical properties. The infiltrated material had an 11 GPa hardness and moderate damage tolerance. It was found that infiltration improved both the ductility and strength of the sintered preforms by eliminating the stress concentration at the interparticle necks.
