Recycled Powders(再生粉末)研究综述
Recycled Powders 再生粉末 - In this study, the microstructure and mechanical properties of a nickel-based superalloy fabricated by laser powder-bed fusion (LPBF) using recycled powders were investigated. [1] There are few comprehensive studies on the microstructure and mechanical properties of SLM-produced parts using recycled powders, especially for maraging steels. [2] The first step in reusing the recycled powders in the 3D printing process is to characterize the microstructure and surface quality of the powder for oxidation and impurity analysis. [3] The possibility to reduce costs of the additive manufacturing (AM) technologies by using recycled powders is still an open question. [4] 4:1, which has the highest efficiency of recycled powders (91. [5] A detailed characterization and comparison of the feedstock and recycled powders is essential in order to understand the number of times a powder can be recycled. [6] On the other hand, flowing properties are similar among the two virgin and recycled powders, with only a significant change in the fraction of fines for SLS material. [7] Lastly, the effect of using fresh or recycled powders, on the microstructure and mechanical properties of DED 316L stainless steel parts is investigated. [8] Reusing the recycled powders can significantly reduce the powder consumption, production cost and time. [9]在这项研究中，研究了使用回收粉末通过激光粉末床熔合 (LPBF) 制造的镍基高温合金的微观结构和机械性能。 [1] 很少有关于使用回收粉末的 SLM 生产零件的微观结构和机械性能的全面研究，特别是对于马氏体时效钢。 [2] 在 3D 打印过程中重复使用回收粉末的第一步是表征粉末的微观结构和表面质量，以进行氧化和杂质分析。 [3] 通过使用回收粉末降低增材制造 (AM) 技术成本的可能性仍然是一个悬而未决的问题。 [4] 4:1，回收粉末效率最高（91. [5] 为了了解粉末可以回收的次数，必须对原料和回收粉末进行详细的表征和比较。 [6] 另一方面，两种原始粉末和回收粉末的流动特性相似，只有 SLS 材料的细粉比例发生显着变化。 [7] 最后，研究了使用新鲜或回收粉末对 DED 316L 不锈钢零件的微观结构和机械性能的影响。 [8] 重复使用回收的粉末可以显着降低粉末消耗、生产成本和时间。 [9]
