Process Window And Microstructural Evolution Of Silica-Reinforced Inconel 718 Metal Matrix Composites Fabricated By Laser Powder Bed Fusion
In this study, fabrication of Inconel 718 (In718) matrix composites reinforced with 1, 2, and 3 wt.% silica nanoparticles by laser powder bed fusion (LPBF) was investigated. To evaluate the LPBF process window, volumetric energy densities, from -30% to +30% relative to the optimized condition of In718, were applied, an...
