摘要：

In this study, porous Inconel 718 alloy (tetrahedral and diamond) were prepared using selective laser melting (SLM), and the compressive deformation behavior was studied. The results showed that both porous structures exhibited a linear elastic deformation stage, a plastic plateau stage, and a densification stage, which were the three stages of ductile porous materials. Tetrahedral porous structures have uneven stress distribution under compression loads, causing shear deformation. A diamond porous structure has uniform stress distribution under compression load, leading to upsetting deformation. When compared with the diamond porous structure, a tetrahedral porous structure shows better compression properties due to the reinforcement effect of the horizontal beam in the tetrahedral structure, which enhances the stiffness and strength of the material.
