The diverse applications of Nd-Fe-B-based magnets are pushing the boundaries of efficiency and miniaturization in various technologies. Metal injection molding (MIM) is emerging as a promising method for producing Nd-Fe-B magnets with intricate geometries. In the article "Binder System Composition on the Rheological and Magnetic Properties of Nd-Fe-B Feedstocks for Metal Injection Molding", published in the special issue "Functional Magnetic Materials and Devices: Recent Advances and Applications" by Applied Sciences, the scientists present their investigations on the influence of the composition of the binder system and the powder loading on the rheological behavior, the degree of contamination and the magnetic properties of Nd-Fe-B MIM parts. A high-pressure capillary rheometer was used to measure the apparent viscosity and pressure drop for different formulations of the material. Oxygen and carbon contamination, density and magnetic properties were also analyzed.
