ABSTRACT This study investigates the use of numerical simulations to describe the solid-state diffusion of a sintering stage during a metal injection moulding process for micro-fluidic components with 316L stainless steel powders. Finite element (FE) analysis based on a thermo-elasto-viscoplastic model was conducted to describe the densification process of a stainless steel porous component during solid-state sintering. The numerical analyses, which were performed on a 3D micro-structured component with various powder volume loadings to take into account the thermal debinding effect to propose a full debinding sintering simulation, demonstrated that the FE simulation results are in agreement with the experimental ones.

烧结微流控器件的实验研究与数值模拟分析

摘要 本研究调查了使用数值模拟来描述 316L 不锈钢粉末微流体组件在金属注射成型过程中烧结阶段的固态扩散。进行了基于热-弹-粘塑性模型的有限元 (FE) 分析，以描述不锈钢多孔部件在固态烧结过程中的致密化过程。数值分析是在具有各种粉末体积负载的 3D 微结构部件上进行的，以考虑热脱脂效应以提出完整的脱脂烧结模拟，表明有限元模拟结果与实验结果一致。
