Abstract: 相应需要进行修改 Aluminum and its alloys are distinguished by their low density, resistance to corrosion, lightweight nature, high specific strength, and impressive thermal conductivity. Their widespread use as essential structural elements for weight reduction signifies their substantial potential in various sectors, including transportation, electronics, healthcare, and the chemical industry.Powder Injection Molding (PIM) of aluminum alloys facilitates the low-cost fabrication of intricately structured, fine aluminum alloy products. This technique offers the benefits of uniform material distribution, precise dimensional accuracy, and heightened raw material utilization, thereby playing 投稿日期:2023-08-03 a critical role in advancing the industrialization of injection-molded aluminum alloy components and expediting their incorporation into electronics and medical devices.This paper presents an overview of the current advancements in aluminum alloy injection molding, and evaluates the preparation prerequisites of feedstock for this process, with an emphasis on binder component design, degreasing strategies, and their atmospheric sintering behavior. We also delve into the role of alloying elements in the sintering densification mechanism. Furthermore, this paper identifies urgent issues and future development directions in the field of aluminum alloy powder injection molding.
